About a year ago, I wrote a piece explaining how much we estimated making Dawnmaker would cost. Well, Dawnmaker is finished, so as promised, I'm going to revisit that and show you how much it actually cost to produce our game! Yay, more money talk!
In June 2023, I made a budget for Dawnmaker that projected the game would cost a total of 520k€ to make. A year later, I can announce that the total budget is around 320k€. Why such a big difference? Because we never managed to secure funding, and thus had to cut a lot of what we wanted to do. We did not hire a team for the production of the game, did not even do the production of the game, did not pay ourselves, and reduced our spending to the minimum.
I'm writing that the budget is 320k€, but that does not mean we actually spent that much money. The amount of money that transited through our bank account and was disbursed is about 95k€. The remaining 225k€ are my estimation for how much Arpentor Studio would have spent if Alexis and I had paid ourselves decent salaries for the whole duration of the project. So in a sense you could say that Dawnmaker only cost 95k€, and there's some truth to that, but it's also a lie. Our work has value and needs to be accounted for in budgeting. Because in the end, this is money that we lost by not doing something else that would have paid us.
Where did the money go?
So we spent 95k€ over the course of 2.5 years. Here are the main expense categories we had:
Even though we barely paid ourselves — we did for 4 months at a time when we thought we were getting a bunch of money, but ultimately did not — salaries are still the biggest category. If you include contracting, which is also paying people to work on our game, that makes up for 60% of the game's budget. The rest is split between Company spending (lawyers, accounting, etc.), events and travel (like going to the Game Camp every year), regular fee for online services (hosting, email, documentation) and a touch of hardware. Plus all the remaining small things that don't fit the other categories, like an ads campaign.
The financial outcome of Dawnmaker
320k€ is an incredibly big sum for such a small company, especially if you compare that to how much the game made. At the time of writing, about 6k€ made it into our bank account. Our players seem to really enjoy Dawnmaker, according to our 94% positive reviews on Steam, so I guess we can call it a critical success. But financially it's far from one: we need another 314k€ to break even!
One metric that I'm thinking about those days, as I prepare the next project, is the revenue per working day. On Dawnmaker, as of writing, Alexis and I made about 6€ per working day. That's less than one tenth of the minimal wage in France, and that's without counting the money that came out of our pockets — otherwise our revenue per day would be negative.
If you're reading this and you're thinking of starting a game studio, here's the biggest advice I can give you: start by making small games. Reduce the risk — the financial cost — by making games that are small, but take them to the finish line. You'll gain experience, you'll make yourself a portfolio that will be helpful to raise funding later, and if you will have a much better chance of having a decent revenue per working day. But I'll discuss this in more details in a future post.
Dawnmaker is 20% off!
Yesterday we released a major, free update for Dawnmaker, our solo turn-based strategy game. We've added 3 characters, each with their own deck and roster of buildings, as well as a ton of new content. To celebrate, we're discounting the game, 20% off for the next two weeks. If you want to experience our city building meets deckbuilding game, now is your time to get it!
This piece was initially sent out to the readers of our newsletter. Wanna join in on the fun? Head out to Dawnmaker's presentation page and fill the form. You'll receive regular stories about how we're making this game and the latest news of its development!

Danielle Moore is a woman on a mission. It shows in the carefully curated, outward-facing books that line the shelves of Semicolon Books in Chicago’s River West neighborhood.
As a lesbian Black woman in a world that often overlooks her, Danielle wanted to build a space where diverse voices are celebrated and independence thrives. “If I want to create it, I will,” she said. For her, that is the definition of independence.
To step into Danielle’s world is to experience solace and peace intended for people seeking a place to simply be. Since it opened in 2019, Semicolon has been a staple in Chicago’s literary community, offering a selection of books that celebrate stories and voices from Black history. This is also reflected in the art and cultural pieces that cover the bookstore’s walls.

“Independence is what creates my safety,” she explained, pointing to the word “independence” tattooed on her left forearm.
With her work, Danielle strives to foster independence in others. One of her goals is to improve youth literacy in Chicago. She frequently donates much of her inventory to book drives for children, as well as for incarcerated individuals across Illinois.
Danielle encourages finding empowerment by building one’s own safe haven, just as she did. “If you’re someone who constantly feels othered, create something,” Danielle advised. “It’s the only way to build a safe mental, emotional and physical space for yourself.”

The experiences that inspired Danielle to open Semicolon began in her childhood. “Books saved my life,” she reflected, remembering a time when the world offered her no other escape. Growing up, Danielle moved between homeless shelters, where books became her refuge. They opened her eyes to endless possibilities and offered life lessons that carried her into adulthood.
Her love for books continues to shape her today. “I’m always reading ‘All About Love’ by bell hooks,” Danielle said. “It’s about love in its truest form — community love — and how you can’t love anybody else if you don’t love yourself. But more than that, it teaches that you can’t claim to love something if you aren’t giving back to the community, ensuring that people feel that love in real, tangible ways.”
Empowering others
<figcaption class="wp-element-caption">Danielle Moore greets a visitor outside Semicolon Books in Chicago. Credit: Jesus J. Montero</figcaption>
Despite facing challenges — whether it’s critics questioning her outward-facing book displays, which isn’t the industry standard, or landlords threatening to raise rent — Danielle remains focused. “I remember sitting in the space, meditating and being reminded that this space isn’t for them,” she says. “This space is for me.”
Building a business, cultivating a community and creating art are all acts of love for Danielle. “Part of that is making sure others feel free to do the same, to carve out their own spaces of joy and expression,” she said.
Expanding her world
Now, as Danielle embarks on new ventures beyond Semicolon’s River West location, she reflects on the journey that brought her here. “Everything always works out,” she said, a personal mantra of sorts.
Semicolon recently opened a new location on the ground floor of the historic Wrigley Building on the Mag Mile. Danielle also plans to launch an outpost in the East Garfield Park neighborhood.
<figcaption class="wp-element-caption">Visitors enjoy the relaxed atmosphere at Semicolon Books in Chicago, whether browsing the shelves or working on laptops. Credit: Jesus J. Montero</figcaption>
Her ambition extends beyond Chicago. In addition to a store in Chicago O’Hare International Airport, Danielle has London and Tokyo locations in her sights.
And as the world expands for Semicolon, so too does its reach online. “The dope part about the internet is that it makes the world small, really fast,” Danielle said. “I can see something incredible, track down the person behind it, and fangirl over them. I love that.” For Danielle, the internet is more than just a tool — it’s a bridge, connecting her with people and communities she might otherwise never encounter.
Owning a bookstore was never part of her original plan, but Danielle now envisions Semicolon becoming the world’s largest independent, nonprofit Black-owned bookseller.
“If I’m not even supposed to be here, I’m gonna do what I want,” she said, determined to spread her message of freedom for all seeking a place to just be.

Freedom and legacy go hand in hand. For entrepreneurs, it means building something that reflects not only their vision but also the stories they want to share with the world.
Husband-and-wife Kevin and Molly Woods embody that philosophy. Their partnership began with a LinkedIn message — one that didn’t lead to a job, but to something much bigger. “She was a recruiter,” Kevin recalled. “You know those messages you always think are a scam? Well, that’s how we met. She sent me one of those 15 years ago, and we’ve been together ever since.”
A new era of creators
<figcaption class="wp-element-caption">The Pop-Up blends style with community-focused retail in Chicago’s Wicker Park. Credit: Jesus J. Montero</figcaption>
Fast forward to today, Kevin and Molly now run The Pop-Up, a resale boutique and creative outlet for local artists, nestled in Chicago’s Wicker Park neighborhood. The store’s mission is rooted in the spirit of collaboration and community. But that path hasn’t been without challenges.
“This space is more than just a store. It’s our home,” Molly shared after their shop was broken into — twice. Yet, through it all, they stayed resilient. The space, once home to the iconic RSVP Gallery where creatives like Don C and the late Virgil Abloh once shaped Chicago’s cultural scene, is now a hub for a new generation of artists and collaborators.
“This isn’t just about selling clothes,” Kevin emphasized. “It’s about creating a space where ideas take flight, where people can come together to celebrate the boundless creativity in this city.”
<figcaption class="wp-element-caption">A vintage yellow Sade t-shirt hangs in The Pop-Up boutique. Credit: Jesus J. Montero</figcaption>
Both Kevin and Molly come from backgrounds in HR, and while they found success in the corporate world, it never quite felt like enough. “We were both HR professionals for years,” Kevin explained, “but we wanted to create something of our own.”
A trip to Japan in 2019 was pivotal. “That trip changed everything for me,” Kevin said. “I came back inspired to create something of my own. I secured the domain as soon as I landed, and that’s when The Pop-Up was born.”
A community-driven comeback
Their dream became a reality, but not without hurdles. After the break-ins, The Pop-Up was forced to close its doors temporarily. However, the community they had poured so much into over the years rallied around them, providing support and encouragement. “It was inspirational to see how everybody in the team rallied together, working through, being resilient, and patient. Knowing that there was light at the end of the tunnel,” Kevin shared.
“They’re not just employees,” Molly added. “They’re family. We’ve watched them grow, their talents blossoming right in front of us.”
<figcaption class="wp-element-caption">Kevin Woods, co-owner of The Pop-Up, organizes clothing on display in their Wicker Park boutique. Credit: Jesus J. Montero</figcaption>
The Pop-Up now thrives as a collaborative space, hosting local designers, artists and small businesses — each contributing to Chicago’s vibrant creative scene. The internet has also played a role in cultivating this community. “It’s definitely a tool,” Kevin said. “It helps us connect. … But at the end of the day, I still believe in that personal interaction to really connect and validate those relationships.”
Now reopened with a fresh design and layout, The Pop-Up continues its mission of supporting local talent and fostering community. Kevin and Molly’s journey is one of resilience and creativity, and their store stands as a testament to the power of collaboration.
“Working with local people to do great things — that’s how we started, and that’s how all of this came to life,” Kevin said, looking ahead to what’s next for The Pop-Up.
With its doors open once again, The Pop-Up is ready to continue adding to Chicago’s rich history and culture in fashion and beyond — one collaboration at a time.

Community is power. That’s the driving force behind DishRoulette Kitchen, a support hub for local food entrepreneurs in Chicago’s Pilsen neighborhood.
DRK was born in 2020, at the height of the COVID-19 pandemic. It started with an observation from Brian Soto, an accountant who saw firsthand how many of his small business clients were ineligible for government relief programs because they lacked the necessary paperwork or tax documentation. “So many of these businesses were shut out of crucial government funding,” explained Chris Cole, DRK’s director of partnerships and communications. “Brian realized that this wasn’t just an issue for his clients, but for small businesses across Chicago.”
Brian partnered with Jackson Flores, and together they founded DRK to address these challenges. The goal was simple: to provide grants, coaching and the financial and operational expertise small businesses needed to survive — and thrive. From helping businesses manage their taxes to offering guidance on rent and payroll, DRK has since become a lifeline for many local entrepreneurs.
“We’re scrappy,” admitted Jackson, DRK’s executive director. “We bootstrapped this entire thing, and we’re going to keep making it happen, no matter what, because the people we serve deserve the chance to thrive, to create the life they’ve always dreamed of.”
Support for real-time challenges
<figcaption class="wp-element-caption">“When an entrepreneur comes in with a problem, we create a roadmap to turn that into a success,” explained Brian Soto, director of finance at DishRoulette Kitchen. Credit: Jesus J. Montero</figcaption>
Each member of the DRK team brings a wealth of experience, including from the corporate, finance, tech and hospitality industries. Now, they’re applying those principles back into the community, giving entrepreneurs the tools they need to succeed. Since its inception, DRK has created a space where self-made entrepreneurs can tap into that corporate expertise and gain the resources they need. The team offers tailored workshops, consultations and one-on-one coaching.
“It’s not just about the business. It’s about the whole person, the family, the community,” said Hector Pardo, DRK’s director of strategy and operations. “When we see one of our entrepreneurs thrive, it’s like popping a bottle of champagne. We’re in this together, and their wins are our wins.”
For many on the team, this work is personal. DRK Program Analyst Melissa Villalba grew up watching her parents’ small business struggle. She knows firsthand how a resource like DRK could have transformed their experience. “Our parents came here with nothing, but they made it work,” Melissa said. “That’s what inspires us — to see what’s possible when you have the right tools and support.”
DRK tailors its guidance to meet the real-time challenges its entrepreneurs face. “When an entrepreneur comes in with a problem, we create a roadmap to turn that into a success,” Brian explained. The team adjusts their lessons as needed, evolving alongside the businesses they support.
Going digital and beyond
<figcaption class="wp-element-caption">Each member of the DRK team brings a wealth of experience, including from the corporate, finance, tech and hospitality industries. Credit: Jesus J. Montero</figcaption>
A key part of that evolution is helping entrepreneurs build and maintain a digital presence, which is crucial in today’s marketplace. “A digital presence is everything for small businesses now,” Chris noted. “We help them not just set up websites, but actually understand how to track their traffic, engage with customers online, and manage sales. We walk them through it one-on-one because too many small business owners don’t get formal training in these areas, and they need someone to show them the ropes.”
DRK’s impact goes beyond just small businesses in Chicago. They’ve worked on national partnerships with major organizations like the James Beard Foundation, and even collaborated on a project with Bad Bunny. But their heart remains rooted in supporting local entrepreneurs.
“We’ve done so many iterations of what we’re doing now, and it’s finally starting to get the attention and support we need,” Jackson added. The team’s diverse leadership is building not only businesses but also a legacy of freedom and opportunity for a new generation of entrepreneurs.
DRK is proof that when local businesses thrive, entire communities benefit. What started as an urgent response to a pandemic-induced crisis has transformed into a vital entrepreneurial hub, one that will continue to create ripple effects throughout Chicago’s neighborhoods for years to come.

As a community builder at Mozilla, I’m all about staying connected — whether that’s producing community events to invite more people into our brand, or working directly with people to make sure our products are actually helping those who need them most. Recently, I had the chance to sit down with three amazing small business owners in Chicago to explore how Solo, Mozilla’s AI-powered website builder, could help them expand their online presence. Solo is built to make creating websites easy, but these sessions were about more than that — they were about building new websites for these small business owners to share their stories and build stronger connections with their communities.
Each of these entrepreneurs had a unique vision for how they wanted to grow their business online. Here’s how we worked together to bring their ideas to life.
Building a digital hub for a community of first-gen entrepreneurs
<figcaption class="wp-element-caption">Soloist.ai/dishroulette showcases the many restaurants that DishRoulette Kitchen is supporting.</figcaption>
Jackson Flores runs DishRoulette Kitchen, an organization that supports first-generation business owners in Chicago’s food scene. DRK already had a website, but they wanted to take things further. Instead of just focusing on DRK, we decided to create a digital hub that showcases the many restaurants they’re helping — many of which didn’t have their own websites.
We built a directory that brings these restaurants together in one space, making it easy for locals to discover new food spots and connect with the people behind the businesses. Working with Jackson was inspiring — her passion for uplifting first-gen entrepreneurs really shone through. The site we built reflects the amazing work DRK is doing in the community, giving more visibility to the businesses they support. You can check out DRK’s Solo website here.
Creating a digital space for a multifaceted career
<figcaption class="wp-element-caption">DanniMoore.com showcases Danielle Moore’s multifaceted career, highlighting her work with Semicolon Books, Single Story Whiskey and her experience in museum and event curation.</figcaption>
Danielle Moore is the owner of Semicolon Books, an independent bookstore in Chicago with a strong community following. Danielle’s work goes far beyond books — she’s also spent 15 years as a museum curator and has recently launched her own whiskey brand. With all these ventures, Danielle needed a website that could tie everything together and present her full story in one cohesive place.
During our session, we built a personal website that allows her to showcase all sides of her career — from books to art to whiskey. Now, her community can see the full scope of her talent, with a site that reflects the many passions that drive her. For Danielle, it was about creating a digital home where her entire journey could come together, offering a complete picture of who she is and what she’s building. You can check out Danielle’s Solo website here.
Turning a long-delayed project into reality
<figcaption class="wp-element-caption">Digital Produce is The Pop-Up founder Kevin Woods’ own streetwear brand.</figcaption>
Kevin is the founder of The Pop-Up, a streetwear business that curates unique pieces from independent brands. While his business is already up and running, he had been working on a new internal line called Digital Produce — a project he’d been passionate about but hadn’t had the time to bring online. Between his full-time job, family, and running the business, creating a website for this new line kept getting delayed. When we sat down to work on it, it felt like the project finally started moving. In just an hour, we built a clean, functional site using Solo that showcases Kevin’s designs, giving his community an easy way to explore his work. For Kevin, the goal was about finally bringing his vision to life after months of putting it off, and giving his brand the platform it deserved. You can check out Digital Produce’s Solo website here.
Building connections, online and beyond
Equipping Jackson, Danielle and Kevin a powerful, free tool like Solo helped each of them find new ways to tell their stories and engage with their communities. With Solo, they’ve created digital spaces that have the potential to strengthen relationships, raise awareness and share their passions in ways they hadn’t before.
Community has always been at the heart of Mozilla’s products, from the early days of Firefox to the tools we’re creating today. Our goal has always been to empower people to shape the internet in ways that reflect who they are and what matters to them. Solo is one part of that effort, giving small business owners the ability to take agency of their digital presence and build meaningful connections with the people around them.

What if, instead of big boring laws intended to cover everything, legislators did more of a do the simplest thing that could possibly work approach?

Yes, the Big Tech companies will try to get small businesses to come out and advocate for surveillance, but there are a bunch of other small business issues that limitations on surveillance could help address, by shifting the balance of power away from surveillance companies.
Are small business owners contending for search rankings and map listings with fake businesses pretending to be competitors in their neighborhood?
Is Big Tech placing bogus charges on their advertiser account–or, if they run ads on their own site, are ad companies docking their pay for unexplained “invalid traffic”?
Are companies taking their content for “AI” that directly competes with their sites—without letting them opt out, or offering an opt-out that would make their business unable to use other services?
Can a small business even get someone from Big Tech on the phone, or are companies putting their dogmatic programs of union-busting and layoffs ahead of service even to advertisers and good business customers?
What happens when an account gets compromised or hacked? Do small businesses have any way to get help (without knowing someone who happens to know someone at the big company?)

A layered approach to content blockingChromium’s Manifest v3 includes the declarativeNetRequest API, which delegates these functions to the browser rather than the extension. Doing so avoids the timing issues visible in privileged extensions and does not require giving the extension access to the page. While these filters are more reliable and improve privilege separation, they are also substantially weaker. You can say goodbye to more advanced anti-adblock circumvention techniques. (Good info on the tradeoffs in Manifest v3, and a possible way forward, with simpler/more secure and complex/more featureful blocking both available to the user)

BRAD SMALLWOOD, SVP AND ANONYM CO-FOUNDER GRAHAM MUDD, SVP OF PRODUCT AND ANONYM CO-FOUNDER
It’s been four months since Anonym joined Mozilla. Anonym was founded with the belief that new technologies can keep digital ads effective and measurable while respecting privacy. Mozilla has long been a leader in digital privacy, so Anonym is happy to report that we are right at home as a key pillar in Mozilla’s strategy to make digital advertising more private. As Laura discussed, while Mozilla’s product teams focus on privacy-respecting advertising tools that are relevant to products like Firefox and Fakespot, we are in parallel focused on building a viable alternative infrastructure for the industry.
Now that we’re settled in, we wanted to provide the advertising industry and the Mozilla community with an overview of the technologies we’re developing and share a few examples of how they can be used to improve user privacy.
First, it’s important for us to be clear about the specific problem we’re trying to address. Digital advertising is highly reliant on user level data sharing between various industry participants. A simple example: Ad platforms collect information about the browsing and buying behavior of individuals from millions of websites and apps. That information is often associated with a user’s “profile” and then is used to determine which ads to show that user. This practice is referred to by a number of terms – tracking, profiling, cross-site sharing, etc.
Whatever the term, this approach typically isn’t aligned with people’s reasonable expectation of privacy. And it’s actually not even necessary to drive ad performance. Anonym’s goal is to develop a better approach for the industry.
Starting at the highest level, we believe there are a few important requirements for any privacy-preserving advertising system. The table below articulates those requirements and the approach Anonym is taking to fulfill them.
Requirement
Anonym’s approach
Security
Data should be processed using confidential computing systems that reduce or eliminate the need to trust any party, including the operator(s) of the technology.
All data processed by Anonym is encrypted end-to-end. Data is processed in Trusted Execution Environments using Intel SGX.
Privacy
The outputs of any privacy-preserving system should protect individuals’ personal data. There must be technical guarantees that reduce or eliminate the possibility of individual’s being re-identified.
Anonym provides aggregated insights and leverages differential privacy to prevent individuals from being singled out.
Transparency
All parties involved should have source-code level transparency into how their data is being processed.
Anonym provides customers with access to detailed documentation and source code through our transparency portal.
Scalability
Advertising is inherently high scale, involving large data sets and millions of businesses. Systems must be capable of processing billions of impressions repeatedly.
Anonym has developed a parallel computing approach using TEEs that can scale arbitrarily to any size job. Our system leverages the same algorithms repeatedly for an unlimited number of customers/campaigns, avoiding manual approval processes.
Diving a bit deeper, the diagram below shows how data flows through Anonym’s system.
Binary Development & Approval: Before any data can be processed, Anonym develops a ‘binary’ which includes all the code for creating a Trusted Execution Environment (TEE) and all the code that will run within it. Binaries are approved by the parties contributing data – and we hope civil society will play a role in this attestation in the future. Typically, a binary is specific to a use case (e.g. attribution) and a media platform (e.g. a social network). The same binary is used by many of that media platform’s customers.
Data Encryption and Transfer: Anonym has a number of tools and methods available to encrypt and transfer data into our environment. Each partner has their own public encryption key – the private key is only available within the TEE. Since the data can’t be decrypted without the private key, it is protected while in transit as well as from Anonym employee access.
Attestation & Decryption: Once an ephemeral TEE has been created customer data is decrypted within its encrypted memory. The key needed for decryption is only available if the binary used by the TEE matches the cryptographic signature of the binary approved by the partner. This provides partners with full control over how Anonym processes their data.
Data Processing & Differential Privacy: Data from two or more sources are joined using shared identifiers. Advertising algorithms such as attribution or lookalike models are run and differential privacy is applied to limit the risk any individual can be identified or singled out.
Aggregated Outputs: The insights are shared with ad platforms and their customers, but no individual user data leaves the TEE. For example, Anonym’s system is used to provide customers with aggregated insights such as which ad creatives are performing best, and ROI calculations for ad campaigns. These insights were previously only available if advertisers exposed user level data directly to ad platforms.
Data & Environment Destroyed: Once the required operations are completed in the TEE, the TEE is destroyed along with all the data within it.
<figcaption class="wp-element-caption">A diagram showing how data flows through Anonym’s system.
</figcaption>
We hope this is a helpful overview of the system we have developed. In the coming weeks, we’ll be publishing deep dives into the components described above. While we believe the system we have developed is a meaningful step forward, we will continue to improve Anonym with feedback from our customers and the privacy community. Please don’t hesitate to reach out if you have questions or would like to learn more.

Here at Mozilla, we are the first to admit the internet isn’t perfect, but we know the internet is pretty darn magical. The internet opens up doors and opportunities, allows for human connection, and lets everyone find where they belong — their corners of the internet. We all have an internet story worth sharing. In My Corner Of The Internet, we talk with people about the online spaces they can’t get enough of, the sites and forums that shaped them, and what reclaiming the internet really looks like.
This month, we’re catching up with Tawanda Kanhema, a journalist and product leader who’s worked across African newsrooms and driven innovation in Silicon Valley. A former Mozillian, he’s currently a board member at the News Product Alliance, where he’s helping empower newsrooms to thrive online. Ahead of the NPA Summit 2024: Tech & Trust, we chatted with Tawanda about his favorite internet rabbit holes (spoiler: creative coding!) and the importance of building strong online communities.
What is your favorite corner of the internet?
The News Product Alliance. It’s a community of product thinkers focused on shaping the future of news. We explore ways to empower newsrooms to strengthen relationships with their communities and design products that enhance how they reach audiences. There are many small newsrooms with limited resources coming up with innovative ways to use available technologies to expand their reach, strengthen their credibility and establish scalable business models.
What is an internet deep dive that you can’t wait to jump back into?
For the last 10 years, I’ve visited a site called Codrops once a week. It’s a community of animation designers and front-end developers sharing demos for others to remix or build on. It’s a great source of inspiration for me, especially when working on digital storytelling. Another site I love is threejs.org, a JavaScript library and application programming interface for creating 3D graphics. NASA even used it for their Mars landing simulation!
What is the one tab you always regret closing?
Honestly, I don’t really regret closing tabs — I use Pocket for everything. All my favorite resources from Codrops and three.js live there, so I can revisit them anytime.
What can you not stop talking about on the internet right now?
I’ve been obsessed with three.js and how it lets you create photorealistic animations with JavaScript and WebGL. For a while, I thought it might even replace some video production workflows, but video still leads in visual communication. Another tool I can’t stop talking about is A-Frame, a web framework that allows you to build 3D virtual worlds in the browser.
What was the first online community you engaged with?
I was part of Google’s Earth Outreach program, focused on how geospatial tools can be used to effect change, and enhance the representation of communities on maps. That led me to mapping projects in Zimbabwe, Namibia and Northern Ontario. It sparked my passion for mapping and documenting underrepresented places.
If you could create your own corner of the internet, what would it look like?
I’ve actually started creating it with Unmapped Planet. It’s an interactive archive of my photography from mapping projects. The site allows users to experience virtual reality tours of the places I’ve mapped. My goal is to create a visual archive and eventually make it more community-focused.
What articles and/or videos are you waiting to read/watch right now?
I have a ton saved in Pocket, mostly around imaging technologies in the generative AI space. I recently completed a Stanford AI course, so I’m diving into articles on how AI is being ethically used in newsrooms. One example is The Baltimore Times’ initiative, led by Paris Brown, to use generative AI create audio versions of the publication’s text stories. This project has expanded access and made The Baltimore Times’ content more accessible to the the community.
With the News Product Alliance creating space for news product builders to connect, how do you think nurturing a community like this can help shape the future of the internet?
We design online experiences that create support networks and connect product thinkers worldwide. And thanks to the power of the community, we are building programs that establish a cycle of support, like our Mentor Network (through which a few other mentors and myself are mentoring current and aspiring newsroom product managers).
The internet has been shaped by the interests of private companies and governments over the last 15 to 20 years, with civic institutions and technology organizations playing the lead role in establishing standards, and communities mostly left out. If we want to change that, we need more diverse communities and change agents ensuring that online content is credible and representative of diverse voices. NPA’s network of over 3,000 professionals is one such community, offering skills development, inspiration and examples of how newsrooms are solving similar problems. For example, we launched a News Product Management Certification program to help people learn product management and apply it in their newsrooms. We’re helping bridge the gap between data-driven decision-making and traditional editorial judgment.
Tawanda Kanhema is a journalist and product manager with a background in reporting across Africa and leading product strategy in Silicon Valley. He previously worked at Mozilla on Pocket and Firefox, connecting millions of users to high-quality content. As a board member of the News Product Alliance, Tawanda focuses on fostering innovation and community among news product builders, helping newsrooms adapt and thrive in the digital age.
Developer Tools help developers write and debug websites on Firefox. This newsletter gives an overview of the work we’ve done as part of the Firefox 131 Nightly release cycle.
Firefox being an open source project, we are grateful to get contributions from people outside of Mozilla:
Mathew Hodson added a link to MDN next to Priority header in the Network Monitor (#1894758)
CSS variables, or CSS custom properties if you’re a spec reader, are fantastic for creating easy reusable values through your pages. To make sure they’re as enjoyable to write in your IDE as to debug in the Inspector, all vendors added a way to quickly see the declaration value of a variable when hovering it in the rule view.
This does work nicely as long as your CSS variable does not depend on other variables. For such cases, the declaration story might not give you a good indication of what is going on.
You’re now left with either going through the different variable declarations to try to map the intermediary values to the final one, or look in the Layout panel to check the computed value for the variable. This is not super practical and requires multiple steps, and you might already be frustrated because you’re chasing a bug for 3 hours now and you just want to go home and relax! That happened to us too many times, so we decided to show the computed value for the variable directly in the tooltip, where it’s easy for you to see (#1626234).
This is even more helpful when you’re using custom registered properties, as the value expression can be properly, well, computed by the CSS engine and give you the final value.
Since we were upgrading the variable tooltip already, we decided to make it look good too, parsing the values the way we do in the rules view already, showing color preview, striking through unused var() and light-dark() parameters, and more (#1912006) !
What’s great with this change is that now that we have the computed value at hand, it’s easy to add color swatch next to variables relying on other variables, which we weren’t doing before (#1630950)
Even better, this allows us to show the computed value of the variable in the autocomplete popup (#1911524)!
While doing this work and reading the spec, I learnt that you can declare empty CSS variables which are valid.
(…) writing an empty value into a custom property, like --foo: ;, is a valid (empty) value, not the guaranteed-invalid value.
It wasn’t possible to add an empty CSS variable from the Rules view, so we fixed this (#1912263). And then, for such empty values, we show an <empty> string so you’re just not left with an empty space, wondering if there’s a bug in DevTools (#1912267, #1912268).
Enhanced Markup and CSS editing
One of my favorite feature in DevTools is the ability to increase or decrease values in the Rules view using the up and down arrows from the keyboard. In Firefox 131 you can now use the mouse wheel to do the same things, and like with the keyboard, holding Shift will make the increment bigger, and holding Alt (Option on OSX) will make the increment smaller (#1801545). Thanks a lot to Christian Sonne, who started this work!
Editing attributes in the markup view was far from ideal as the differences between an element attribute being focused and the initial state of attribute inputs was almost invisible, even to me. This wasn’t great, especially with all our work on focus indicator which aims to bring clarity to users, so we improved the situation by changing the style of the selected node when an attribute is being modified, which should help make editing less confusing (#1501959, #1907803, #1912209)
<figcaption class="wp-element-caption">Firefox 130 on the left, and Firefox 131 on the right. On the top, the class attribute being focused with the keyboard, on the bottom, the class attribute being edited via an input, with its content selected. On the left, there’s almost no visible differences between the two states.</figcaption>
Bug fixes
In Firefox 127, we did some changes to improve performance of the markup view, including how we detect if we should show the event badge on a given element. Unfortunately we also completely broke the event badge if the page was using jQuery and Array prototype was extended, for example by including Moo.js. This is fixed in this Firefox 131 and in ESR 128 as well (#1916881)
We got a report that enabling the grid highlighter in some specific conditions would stress GPU and CPU, as we were triggering too many reflows, as we were working around platform limitation to avoid rendering issues. This limitation is now gone and we can save up cycle and avoid frying your GPU (#1909170).
Finally, we made selecting a <video> element using the node picker not play/pause said video (#1913263).
And that’s it for this months folks, Thank you for reading this and using our tools, see you in a few weeks for a new round of updates
Full list of fixed bugs in DevTools for the Firefox 131 release:
Nicolas Chevobbe [:nchevobbe] Rule view shows CSS variable value in declaration instead of declaration text when variable uses light-dark() (#1911525)
Nicolas Chevobbe [:nchevobbe] Registered properties value with CSS wide keywords (inherit, unset, initial, revert, revert-layer) are indicated as invalid at computed value time (#1911619)
As Mark shared in his blog, Mozilla is going to be more active in digital advertising. Our hypothesis is that we need to simultaneously work on public policy, standards, products and infrastructure. Today, I want to take a moment to dive into the details of the “product” and “infrastructure” elements. I will share our emerging thoughts on how this will come to life across our existing products (like Firefox), and across the industry (through the work of our recent acquisition, Anonym, which is building an alternative infrastructure for the advertising industry).
Across both pillars (product and infrastructure), we maintain the same goal – to build digital advertising solutions that respect individuals’ rights. Solutions that achieve a balance between commercial value and public interest. Why is that something for Mozilla to address? Because Mozilla’s mission is to build a better internet. And, for the foreseeable future at least, advertising is a key commercial engine of the internet, and the most efficient way to ensure the majority of content remains free and accessible to as many people as possible.
Right now, the tradeoffs people are asked to make online are too significant. Yes, advertising enables free access to most of what the internet provides, but the lack of practical control we all have over how our data is collected and shared is unacceptable. And solutions to this problem that simply rely on handing more of our data to a few gigantic private companies are not really solutions that help the people who use the internet, at all.
These are the problems Mozilla hopes to address, through a product strategy that is grounded on our core principles of privacy, openness and choice. We know that not everyone in our community will embrace our entrance into this market. But taking on controversial topics because we believe they make the internet better for all of us is a key feature of Mozilla’s history. And that willingness to take on the hard things, even when not universally accepted, is exactly what the internet needs today.
Demonstrating a way forward through our own products
One of the most obvious places we will do this work is across our own products, including Firefox, Fakespot, and likely new efforts in the future. Advertising on our products will remain focused on respecting the privacy of the people who use them. Those are table stakes for us, fundamental qualities which will be our north star. From a technical perspective, we will be developing and utilizing advanced cryptographic and aggregation techniques. Through the testing, iteration and deployment of those techniques, we seek to both improve our standardization efforts and prove to the industry at large that advertising can sustain a business without exposing the personal data of every individual online.
As part of this work, we are also committing to being transparent and open about our intent and plans prior to launching tests or features. With that, I want to build on the apology Mark made in his blog. Several weeks ago, and before we explained our intent of how the technology was intended to work, we landed some code in Firefox as part of an origin trial of Privacy Preserving Attribution (PPA). While the trial was never activated for external users, this understandably led to confusion and concern that we are working to address. We will redouble our engagement with regulators and civil society to address any concerns. There will be much more to come about our work within our products, and you will have time to ask questions and give us feedback.
Building better technology for the industry
In parallel to our existing consumer products, we have the opportunity to build a better infrastructure for the online advertising industry as a whole. Advertising at large cannot be improved unless the tech it’s built upon prioritizes securing user data. This is precisely why we acquired Anonym.
Anonym is building technology that can provide more privacy-preserving infrastructure for data sharing between advertisers and publishers, in a way that also supports a level playing field rather than consolidating data in a few large companies.
Advertising will not improve unless we address the underlying data sharing issues, and solve for the economic incentives that rely on that data. We want to reshape the industry so that aggregated population insights are the norm instead of platforms sharing individual user data with each other indiscriminately.
Anonym is building the technology needed to enable that, with privacy-preserving techniques such as differential privacy, which adds calibrated noise to data sets so that the individual user data is kept as private as possible, while still being useful in aggregate. Calculations on that data occur in secure and private environments. The system is designed such that humans don’t have access to individual data. The outputs are aggregated and anonymized, then Anonym destroys the individual data. This pragmatic solution inspires us to envision a world in which digital ads can be both effective and privacy-preserving. It’s not impossible.
A better future
As I said earlier in this blog, we do this fully acknowledging our expanded focus on online advertising won’t be embraced by everyone in our community, and knowing that as we create innovative approaches we will need to account for our users’ evolving expectations. That’s never a comfortable position to be in, but we firmly believe that building a better future for online advertising is critical to our overall goal of building a better future for the internet. I would rather have a world where Mozilla is actively engaged in creating positive solutions for hard problems, than one where we only critique from the sidelines. We will continue to work with others to grapple with the bigger question of how to find alternative solutions to advertising for funding the internet’s future, but we cannot afford to ignore the reality we live in now.
But that does not mean any of us should have to accept the broken advertising models we have today. As we’ve done throughout our history, Mozilla will pave the road to a better future through influencing public policy, improving standards, and through actively creating better products and infrastructure. And, most importantly, we will do this together with the thousands of other companies, advocates, policymakers and concerned internet users who are seeking better options and more control over their online experiences.
Keeping the internet, and the content that makes it a vital and vibrant part of our global society, free and accessible has been a core focus for Mozilla from our founding. How do we ensure creators get paid for their work? How do we prevent huge segments of the world from being priced out of access through paywalls? How do we ensure that privacy is not a privilege of the few but a fundamental right available to everyone? These are significant and enduring questions that have no single answer. But, for right now on the internet of today, a big part of the answer is online advertising.
We started engaging in this space because the way the industry works today is fundamentally broken. It doesn’t put people first, it’s not privacy-respecting, and it’s increasingly anti-competitive. There have to be better options. Mozilla can play a key role in creating these better options not just by advocating for them, but also by actually building them. We can’t just ignore online advertising — it’s a major driver of how the internet works and is funded. We need to stare it straight in the eyes and try to fix it. For those reasons, Mozilla has become more active in online advertising over the past few years.
We have the beginnings of a theory on what fixing it might look like — a mix of different business practices, technology, products, and public policy engagements. And we have started to do work on all of these fronts. It’s been clear to us in recent weeks that what we haven’t done is step back to explain our thinking in the broader context of our advertising efforts. For this, we owe our community an apology for not engaging and communicating our vision effectively. Mozilla is only Mozilla if we share our thinking, engage people along the way, and incorporate that feedback into our efforts to help reform the ecosystem.
We’re going to correct that, starting with this blog post. I want to lay out our thinking about how we plan to shift the world of online advertising in a better direction.
Our theory
As we say in our Manifesto: “…a balance between commercial profit and public benefit is critical … “ to creating an open, healthy internet. Through that balance, we can have an internet that protects privacy and access, while encouraging a vibrant market that rewards creativity and innovation. But that’s not what we have in online advertising today.
Our theory for improving online advertising requires work across three areas that relate to and build upon one another:
Regulation: Over the years, improving privacy and consumer protection in advertising while enabling competition has been at the core of our policy efforts. From pushing to improve Google’s Privacy Sandbox proposals via engaging with the Competition and Markets Authority (CMA) in the UK to advocating for strong protections for universal opt-out mechanisms via state privacy laws in the United States, we have a long history of supporting legislation that puts users in more meaningful control of their data. We recognise that technology can only get us so far and needs to work hand-in-hand with legislation to fix the most egregious practices in the ecosystem. With the upcoming new mandate in the European Commission expected to focus on advertising and the push for a federal privacy legislation in the United States reaching a fever pitch, we intend to build upon this work to continue pushing for better privacy protections.
Standards: As a pioneer in shaping internet standards, Mozilla has always played a central role in crafting technical specifications that support an open, competitive, and privacy-respecting web. We are bringing this same expertise and commitment to the advertising space. At the Internet Engineering Task Force (IETF) and World Wide Web Consortium (W3C), Mozilla is actively involved in advancing cutting-edge proposals for privacy-preserving advertising. This includes collaborating on Interoperable Private Attribution (IPA) and contributing to the Private Advertising Technology Community Group (PATCG). The goal of this work is to identify legitimate, lawful, and non-harmful use cases and promote a healthy web by developing privacy-respecting technical mechanisms for those use cases. This would make it practical to more strictly limit the most invasive practices like ubiquitous third-party cookies.
Products: Building things is the only way for Mozilla to prove these hypotheses. For years, Mozilla products have supported an advertising business without the privacy-invasive techniques common today by deploying features such as Total Cookie Protection and Enhanced Tracking Protection to protect our users. And we’ll continue to explore ways to add advertiser value while respecting user privacy – including by exploring how we can support other businesses in achieving these goals via Anonym. Our goal is to build a model to demonstrate how ads can sustain a business online while respecting people’s privacy. Laura expands upon our approach in her blog.
We have work underway right now across all three of these areas, with much more to come in the weeks and months ahead.
The way forward — together
This theory, and the work to test it, will become an increasingly integral part of the discussions we already have underway with regulators and civil society, consumers and developers, and advertisers, publishers and platforms. We will continue to set up gatherings, share research, and explore new ways to collectively share ideas and move this ahead for all of us – both shaping and being shaped by the ecosystem.
Fixing the problems with online advertising feels like an intractable challenge. Having been fortunate enough to be part of Mozilla for well over a decade, I am excited to tackle this challenge head on. It’s an opportunity for us to bring a whole community — including often divergent voices from advertising, technology, government and civil society — to the table to look for a better way. Personally, I don’t see a world where online advertising disappears — ads have been a key part of funding creators and publishers in every era from newspapers to radio to television. However, I can imagine a world where advertising online happens in a way that respects all of us, and where commercial and public interests are in balance. That’s a world I want to help build.
In today’s fast-moving AI landscape, choosing the right large language model (LLM) for your project can feel like navigating a maze. With hundreds of models, each offering different capabilities, the process can be overwhelming. That’s why Mozilla.ai is developing Lumigator, a product designed to help developers confidently select the best LLM for their specific project. It’s like having a trusty compass for your AI journey.
The problem (and why we’re tackling it)
As more organizations turn to AI for solutions, they face the challenge of selecting the best model from an ever-growing list of options. The AI landscape is evolving rapidly, with twice as many new models released in 2023 compared to the previous year. Yet, in spite of the wealth of metrics available, there’s still no standard way to compare these models.
The 2024 AI Index Report highlighted that AI evaluation tools aren’t (yet) keeping up with the pace of development, making it harder for developers and businesses to make informed choices. Without a clear single method for comparing models, many teams end up using suboptimal solutions, or just choosing models based on hype, slowing down product progress and innovation.
Our mission (and how we’re getting started)
With Lumigator MVP, Mozilla.ai aims to make model selection transparent, efficient, and empowering. Lumigator provides a framework for comparing LLMs, using task-specific metrics to evaluate how well a model fits your project’s needs. With Lumigator, we want to ensure that you’re not just picking a model—you’re picking the right model for your use case.
Our vision for the future
In the future, Lumigator will grow beyond evaluation into a full-blown open-source product for ethical and transparent AI development and fill in gaps in the AI development tooling landscape in the industry. We want to create a space where developers can trust the tools they use, knowing they’re building solutions that align with their values.
Our MVP is just the start. While we’re focused on model selection now, we’re building towards something much bigger. Lumigator’s ultimate goal is to become the go-to open-source platform for developers who want to make sure they’re using AI in a way that is transparent, ethical, and aligned with their values. With the input of the community, we’ll continue to expand beyond evaluation and text summarization into all aspects of AI development. Together, we’ll shape Lumigator into a tool that you can trust.
With Lumigator, we want to democratize AI. What do we mean by this? We want to make advanced technologies available to both developers and to organizations of all sizes. Our mission is to enable people to build solutions that leverage AI to align with their goals and values—whether it’s fostering transparency, driving innovation, or creating a more inclusive future for AI.
Hello Thunderbird Community! I’m Toby Pilling, a new team member and I’ve spent the last couple of months getting up to speed, and have really enjoyed meeting the team and members of the community virtually, and some in person! September is now over (and so is the summer for many in our team), and we’re excited to share the latest adventures underway in the Thunderbird world. If you missed our previous update, go ahead and catch up! Here’s a quick summary of what’s been happening across the different teams:
Exchange
Progress continues on implementing move/copy operations, with the ongoing re-architecture aimed at making the protocol ecosystem more generic. Work has also started on error handling, protocol logging and a testing framework. A Rust starter pack has been provided to facilitate on-boarding of new team members with automated type generation as the first step in reducing the friction.
Account Hub
Development of a refreshed account hub is moving forward, with design work complete and a critical path broken down into sprints. Project milestones and tasks have been established with additional members joining the development team in October. Meta bug & progress tracking.
Global Database & Conversation View
The team is focused on breaking down the work into smaller tasks and setting feature deliverables. Initial work on integrating a unique IMAP ID is being rolled out, while the conversation view feature is being fast-tracked by a focused team, allowing core refactoring to continue in parallel.
In-App Notification
This initiative will provide a mechanism to notify users of important security updates and feature releases “in-app”, in a subtle and unobtrusive manner, and has advanced at break-neck speed with impressive collaboration across each discipline. Despite some last-minute scope creep, the team has moved swiftly into the testing phase with an October release in mind. Meta Bug & progress tracking.
Source Docs Clean-up
Work continues on source documentation clean-up, with support from the release management team who had to reshape some of our documentation toolset. The completion of this project will move much of the developer documentation closer to the actual code which will make things much easier to maintain moving forwards. Stay tuned for updates to this in the coming week and follow progress here.
Account Cross-Device Import
As the launch date for Thunderbird for Android gets closer, we’re preparing a feature in the desktop client which will provide a simple and secure account transfer mechanism, so that account settings don’t have to be re-entered for new users of the Android client. A functional prototype was delivered quickly. Now that design work is complete, the project entered the 2 final sprints this week. Keep track here.
Battling OAuth Changes
As both Microsoft and Google update their OAuth support and URLs, the team has been working hard to minimize the effect of these changes on our users. Extended logging in Daily will allow for better monitoring and issue resolution as these updates roll out.
New Features Landing Soon
Several requested features are expected to debut this month or very soon:
Encrypted draft messages even when no recipients are specified.
UI enhancements and bug fixes for the calendar, RSS, and mail modules.
As usual, if you want to see things as they land you can check the pushlog and try running daily. This would be immensely helpful for catching bugs early.
We’ve also started working on the intrinsic sizing keywords ‘min-content’, ‘max-content’, ‘fit-content’, and ‘stretch’ (@Loirooriol, @mrobinson, #33492).
Before we can support them, though, we needed to land patches to calculate intrinsic sizes, including for percent units (@Loirooriol, @mrobinson, #33204), aspect ratios of replaced elements (@Loirooriol, #33240), column flex containers (@Loirooriol, #33299), and ‘white-space’ (@Loirooriol, #33343).
We’ve also worked on our WebGPU support, with support for pipeline-overridable constants (@sagudev, #33291), and major rework to GPUBuffer (@sagudev, #33154) and our canvas presentation (@sagudev, #33387).
As a result, GPUCanvasContext now properly supports (re)configuration and resize on GPUCanvasContext (@sagudev, #33521), presentation is now faster, and both are now more conformant with the spec.
Performance and reliability
Servo now sends font data over shared memory (@mrobinson, @mukilan, #33530), saving a huge amount of time over sending font data over IPC channels.
We now debounce resize events for faster window resizing (@simonwuelker, #33297), limit document title updates (@simonwuelker, #33287), and use DirectWrite kerning info for faster text shaping on Windows (@crbrz, #33123).
We’ve also added a new profiling Cargo profile that builds Servo with the recommended settings for profiling (@delan, #33432).
For more details on building Servo for profiling, benchmarking, and other perf-related use cases, check out our updated Building Servo chapter (@delan, book#22).
script is the heart of the Servo rendering engine — it contains the HTML event loop plus all of our DOM APIs and their bindings to SpiderMonkey, and the script thread drives the page lifecycle from parsing to style to layout.
script is also a monolith, with over 170 000 lines of hand-written Rust plus another 520 000 lines of generated Rust, and it has long dominated Servo’s build times to the point of being unwieldy, so it’s very exciting to see that we may be able to change this.
Contributors to Servo can now enjoy faster self-hosted CI runners for our Linux builds (@delan, @mrobinson, #33321, #33389), cutting a typical Linux-only build from over half an hour to under 8 minutes, and a typical T-full try job from over an hour to under 42 minutes.
We’ve also fixed several HiDPI bugs in servoshell (@mukilan, #33529), as well as keyboard input and scrolling on Windows (@crbrz, @jdm, #33225, #33252).
Donations
Thanks again for your generous support!
We are now receiving 4147 USD/month (+34.7% over July) in recurring donations.
This includes donations from 12 people on LFX, but we will stop accepting donations there soon — please move your recurring donations to GitHub or Open Collective.
Servo is also on thanks.dev, and already eleven GitHub users that depend on Servo are sponsoring us there.
If you use Servo libraries like url, html5ever, selectors, or cssparser, signing up for thanks.dev could be a good way for you (or your employer) to give back to the community.
4147 USD/month
10000
With this money, we’ve been able to pay for our web hosting and self-hosted CI runners for Windows and Linux builds, and when the time comes, we’ll be able to afford macOS runners, perf bots, and maybe even an Outreachy intern or two!
As always, use of these funds will be decided transparently in the Technical Steering Committee.

I am turning off the controversialPrivacy-preserving attribution (PPA) advertising tracking feature in Firefox, even though, according to the documentation, there are some good things about PPA compared to cookies:
You can’t be identified individually as the same person who saw an ad and then bought something
A site can’t tell if you have PPA on or off
Those are both interesting and desirable properties, and the PPA system, if implemented correctly and run honestly, does not look like a problem on its own. So why are people creeped out by it? That creeped-out feeling is not coming from privacy math ignorance, it’s people’s inner behavioral economists warning about an information imbalance. Just like people who grow up playing ball can catch a ball without consciously doing calculus, people who grow up in market economies get a pretty good sense of markets and information, which manifests as a sense of being creeped out when something about a market design doesn’t seem right.
The problem is not the design of PPA on its own, it’s that PPA is being proposed as something to run on the real Web, a place where you can find both the best legit ad-supported content and the most complicated scams. And that creates a PPA paradox: this privacy-preserving attribution feature, if it catches on, will tend to increase the amount of surveillance. PPA doesn’t have all of the problems of privacy-enhancing technologies in web browsers, but this is a big one.
Briefly, the way that PPA is designed to work is that sites that run ads will run JavaScript to request that the browser store impression events to keep a record of the ad you saw, and then a site where you buy stuff can record a conversion and then get a report to find out which sites the people who bought stuff had seen ads on. The browser doesn’t directly share the impression events with the site where you buy stuff. It generates an encrypted message that might or might not include impressions, then the site passes those encrypted messages to secure services to do math on them and create an aggregated report. The report doesn’t make it possible to match any individual ad impression to any individual sale.
So, as a web entrepreneur willing to bend the rules, how would you win PPA? You could make a site where people pay attention to the ads, and hope that gets them to buy stuff, so you get more ad money that way. The problem with that is that legit ad-supported content and legit, effective advertising are both hard. Not only do you need to make a good site, the advertisers who run their ads on it need to make effective ads in order for you to win this way. And with the ongoing collapse of business norms, growth hackers do just as well as legit businesses anyway. So an easier way to win the PPA game is to run a crappy site and then (1) figure out who’s about to buy, (2) trick those people into visiting your crappy site, and (3) tell the browser to store an impression before the sale you predicted, so that your crappy site gets credit for making the sale. And steps 1 and 2 work better and better the more surveillance you can do, including tracking people between web and non-web activity, smart TV mics, native mobile SDKs, server-to-server CAPIs, malware, use your imagination.
Of course, attribution stealing schemes are a thing with conventional cookie and mobile app tracking, too. And they have been for quite a while. But conventional tracking generally produces enough extra info to make it possible to do more interesting attribution systems that enable marketers to figure out when legit and not-so-legit conversions are happening. If you read Mobile Dev Memo by Eric Seufert and other high-end marketing sites, there is a lot of material about more sophisticated atribution models than what’s possible with PPA. Marketers have a constant set of stats problems to solve to figure out which of the ads are going to influence people in the direction of buying stuff, and which ad money is being wasted because it gets spent on claiming credit for selling a thing that customers were going to buy anyway. PPA doesn’t provide the info needed to get good answers for those stats problems—so what works like a privacy feature on its own would drive the development and deployment of more privacy risks. I’m turning it off, and I hope that enough people will join me to keep PPA from catching on.

How do Twitch streamers connect with so many people on the internet while keeping their personal lives private?
For those unfamiliar, Twitch streamers are content creators who broadcast live to audiences in real-time, covering everything from gaming to productivity. Viewer interaction is a huge part of the experience, but it also opens up streamers to risks like “doxxing,” where someone digs up and shares private info like real names or addresses.
As a writer and photographer, I thought I was prepared when I started streaming. I’ve had an online presence for years, and I’m familiar with the ins and outs of social media. But when you’re live, sharing your screen and constantly interacting with viewers, protecting your privacy becomes a whole new challenge. To figure out how the pros do it, I reached out to some streamers who’ve mastered the art of staying safe online.

1. Dox yourself before someone else does
Before anyone else can dig up your personal information, look yourself up and lock it down.
You might be surprised by old social media accounts, blogs or posts that you forgot about. Take the time to track down and clean up these loose ends — it’s a proactive way to keep your personal details from falling into the wrong hands.
As @DANGERD0RK explains, “Due to the nature and risks the internet poses, you may end up putting not just yourself, but others, at risk by not protecting your personal information such as name, address, place of work, city you live in, phone number, social media accounts and your whereabouts when discussing your day with others.”
To protect yourself, banning personal keywords on stream is crucial. Twitch lets streamers set filters for specific words or phrases that viewers aren’t allowed to say in chat — like your full name, hometown or other private details. @DANGERD0RK also recommends ”creating separate social media accounts so others will not be able to look at your history of posts, tagged friends, family members or other information that can be used to dox you.”

2. Treat every online interaction like an open window — be mindful of what’s in view
Whether you’re streaming, sharing your screen in a meeting or posting on social media, it’s easy to reveal more than you realize.
“My primary content right now is productivity streaming! I am essentially ‘LoFi Girl’ but live,” says @sweetxsage. “So for me, I just have to be careful to not share my screen on accident, or show specific angles that might let people know what area I live in, and I also recently noticed I shouldn’t talk too much about ‘local’ food spots because it could help pinpoint where I live. Even casual conversations can reveal more than I’d like to share.”
Always imagine every moment of your stream or interaction as an open window into your life. What’s unintentionally being shared?
@DANGERD0RK says, “Clicking on a link may dox your private information, looking up a restaurant name may give away your location, and ‘autofill’ options [on your browser] may inadvertently show your information.”
3. Layer your privacy defenses like a pro
Think like a pro streamer and protect yourself with layers of privacy controls.
It’s important to use tools and settings that allow you to control who can see your information and prevent accidental sharing. Streamers often rely on a combination of software, hardware and privacy settings to keep their streams professional and secure. For example, as @sweetxsage shared, having the right setup allows for flexibility and enjoyment: “[A]s long as I can have [my core] things, my stream can be fun and entertaining.”
In addition to your streaming setup, using a privacy-focused browser can make a big difference. Firefox helps block trackers by default, giving you more control over your data and protecting you from tracking and unwanted access. (Firefox also comes from Mozilla, which is dedicated to maintaining user privacy, making the internet a safer place for all, and promoting civil discourse, human dignity and individual expression.)
If you’re worried about past data breaches, Mozilla Monitor is another tool that helps you stay ahead of potential leaks and keep track of any issues with your personal information.
Whether you’re streaming or just hanging out online, it’s all about finding that balance — sharing what you want while keeping the important stuff private. With a few smart privacy moves and some advice from streamers like @sweetxsage and @DANGERD0RK, you can keep things fun, safe and under control. After all, making connections doesn’t mean sharing it all.
We’ve just released Thunderbird version 128, codenamed “Nebula”, our yearly stable release. So with that big milestone done, I wanted to take a moment and tell our community about the state of Thunderbird. In the past I’ve done a recap focused solely on the project’s financials, which is interesting – but doesn’t capture all of the great work that the project has accomplished. So, this time, I’m going to try something different. I give you the State of the Bird: Thunderbird Annual Report 2023-2024.
Before we jump into it, on behalf of the Thunderbird Team and Council, I wanted to extend our deepest gratitude to the hundreds of thousands of people who generously provided financial support to Thunderbird this past year. Additionally, Thunderbird would like to thank the many volunteers who contributed their time to our many efforts. It is not an exaggeration to say that this product would not exist without them. All of our contributors are the lifeblood of Thunderbird. They are the beacons shining brightly to remind us of the transformative power of open source, and the influence of the community that stands alongside it. Thank you for not just being on this journey with us, but for making the journey possible.
Supernova & Nebula
Thunderbird Supernova 115 blazed into existence on July 11, 2023. This Extended Support Release (ESR) not only introduced cool code names for releases, but also helped bring Thunderbird a modern look and experience that matched the expectation of users in 2023. In addition to shedding our outdated image, we also started tackling something which prevented a brisk development pace and steady introduction of new features: two decades of technical debt.
After three years of slow decline in Daily Active Users (DAUs), the Supernova release started a noticeable upward trend, which reaffirms that the changes we made in this release are putting us on the right track. What our users were responding to wasn’t just visual, however. As we’ve noted many times before – Supernova was also a very large architectural overhaul that saw the cleanup of decades of technical debt for the mail front-end. Supernova delivered a revamped, customizable mail experience that also gave us a solid foundation to build the future on.
Fast forwarding to Nebula, released on July 11, 2024, we built upon many of the pillars that made Supernova a success. We improved the look and feel, usability, customization and speed of the mail experience in truly substantial ways. Additionally, many of the investments in improving the Thunderbird codebase began to pay dividends, allowing us to roll in preliminary Exchange support and use native OS notifications.
All of the work that has happened with Supernova and Nebula is an effort to make Thunderbird a first-class email and productivity tool in its own right. We’ve spent years paying down technical debt so that we could focus more on the features and improvements that bring value to our users. This past year we got to leverage all that hard work to create a truly great Thunderbird experience.
K-9 Mail & Thunderbird For Android
In response to the enormous demand for Thunderbird on a phone, we’ve worked hard to lay a solid foundation for our Android release. The effort to turn K-9 Mail into something we can confidently call a great Thunderbird experience on-the-go is coming along nicely.
In April of 2023, we released K-9 6.600 with a message view redesign that brought K-9 and Thunderbird more in line. This release also had a more polished UI, among other fixes, improvements, and changes. Additionally, it integrated our new design system with reusable components that will allow quicker responses to future design changes in Android.
The 6.7xx Beta series, developed throughout 2023, primarily focused on improving account setup. The main reason for this change is to enable seamless email account setup. This also started the transition of K-9’s UI from traditional Android XML layouts to using the more modern and now recommended Jetpack Compose UI toolkit, and the adoption of Atomic Design principles for a cohesive, intuitive design. The 6.710 Beta release in August was the first to include the new account setup for more widespread testing. Introducing new account setup code and removing some of the old code was a step in the right direction.
In other significant events of 2023, we hired Wolf Montwé as a senior software engineer, doubling the K-9 Mail team at MZLA! We also conducted a security audit with 7ASecurity and OSTIF. No critical issues were found, and many non-critical issues were fixed. We began experimenting with Material 3 and based on positive results, decided to switch to Material 3 before renaming the app. Encouraged by our community contributors, we moved to Weblate for localization. Weblate is better integrated into K-9 and is open source. Some of our time was also spent on necessary maintenance to ensure the app works properly on the latest Android versions.
So far this year, we’ve shipped the account setup improvements to everyone and continued work on Material 3 and polishing the app in preparation for its transition to “Thunderbird for Android.” You can look at individual release details in our GitHub repository and track the progress we’ve made there. Suffice to say, the work on creating an amazing Android experience has been significant – and we look forward to sharing the first true Thunderbird release on Android in the next few months.
Services and Infrastructure
In 2023 we began working in earnest on delivering additional value to Thunderbird users through a suite of web services. The reasoning? There are some features that would add significant value to our users that we simply can’t do in the Thunderbird clients alone. We can, however, create amazing, open source, privacy-respecting services that enhance the Thunderbird experience while aligning with our values – and that’s what we’ve been doing.
The services that we’ve focused on are: Appointment, a calendar scheduling tool; Send, an encrypted large-file transfer service; and Thunderbird Sync, which will allow users to sync their Thunderbird settings between devices (both desktop and Android).
Thunderbird Appointment enables you to plan less and do more. You can add your calendars to the service, outline your weekly availability and then send links that allow others to grab time on your schedule. No more long back-and-forth email threads to find a time to meet, just send a link. We’ve just opened up beta testing for the service and look forward to hearing from early users what features our users would like to see. For more information on Thunderbird Appointment, and if you’d like to sign up to be a beta tester, check out our Thunderbird Appointment blog post. If you want to look at the code, check out the repository for the project on GitHub.
The Thunderbird team was very sad when Firefox Send was shut down. Firefox Send made it possible to send large files easily, maybe easier than any other tool on the Internet. So we’re reviving it, but not without some nice improvements. Thunderbird Send will not only allow you to send large files easily, but our version also encrypts them. All files that go through Send are encrypted, so even we can’t see what you share on the service. This privacy focus was important in building this tool because it’s one of our core values, spelled out in the Mozilla Manifesto (principle 4): “Individuals’ security and privacy on the internet are fundamental and must not be treated as optional.”
Finally, after many requests for this feature, I’m happy to share that we are working hard to make Thunderbird Sync available to everyone. Thunderbird Sync will allow you to sync your account and application settings between Thunderbird clients, saving time at setup and headaches when you use Thunderbird on multiple devices. We look forward to sharing more on this front in the near future.
2023 Financial Picture
All of the above work was made possible because of our passionate community of Thunderbird users. 2023 was a year of significant investment into our team and our infrastructure, designed to ensure the continued long-term stability and sustainability of Thunderbird. As previously mentioned these investments would not have been possible without the remarkable generosity of our financial contributors.
Contribution Revenue
Total financial contributions in 2023 reached $8.6M, reflecting a 34.5% increase over 2022. More than 515,000 transactions from over 300,000 individual contributors generated this financial support (26% of the transactions were recurring monthly contributions).
In addition to that incredible total, what stands out is that the majority of our contributions were modest. The average contribution amount was $16.90, and the median amount was $11.12.
We are often asked if we have “super givers” and the refreshing answer is “no, we simply have a super community.” To underscore this, consider that 61% of giving was $20 or less, and 95% of the transactions were $35 or less. The number of transactions $1000 and above accounted for only 56 transactions; that’s effectively 0.0007% of all contribution transactions.
And this super community helping us sustain and improve Thunderbird is very much a global one, with contributions pouring in from more than 200 countries! The top five giving countries — Germany, the United States, France, the United Kingdom, and Japan — accounted for 63% of our contribution revenue and 50% of transactions. We believe this global support is a testament to the universal value of Thunderbird and the core values the project stands for.
Expenses
Now, let’s talk about how we’re using these funds to keep Thunderbird thriving well into the future.
As with most organizations, employee-related expenses are the largest expense category. The second highest category for us are all the costs associated with distributing Thunderbird to tens of millions of users and the operations that help make that happen. You can see our spending across all categories below:
The Importance of Supporting Thunderbird
When I started at Thunderbird (in 2017), we weren’t on a sustainable path. The cost of building, maintaining and distributing Thunderbird to tens of millions of people was too great when compared against the financial contributions we had coming in. Fast forward to 2023 and we’re able to not only deliver Thunderbird to our users without worrying about keeping the lights on, but we are able to fix bugs, build new features and invest in new platforms (Android). It’s important for Thunderbird to exist because it’s not just another app, but one built upon real values.
Our values are:
We believe in privacy. We don’t collect your data or spy on you, what you do in Thunderbird is your business, not ours.
We believe in digital wellbeing. Thunderbird has no dark patterns, we don’t want you doomscrolling your email. Apps should help, not hurt, you. We want Thunderbird to help you be productive.
We believe in open standards. Email works because it is based on open standards. Large providers have undermined these standards to lock users into their platforms. We support and develop the standards to everyone’s benefit.
If you share these values, we ask that you consider supporting Thunderbird. The tech you use doesn’t have to be built upon compromises. Giving to Thunderbird allows us to create good software that is good for you (and the world). Consider giving to support Thunderbird today.
2023 Community Snapshot
As we’ve noted so many times in the previous paragraphs, it’s because of Thunderbird’s open source community that we exist at all. In order to better engage with and acknowledge everyone participating in our projects, this past year we set up a Bitergia instance, which is now public. Bitergia has allowed us to better measure participation in the community and find where we are doing well and improving, and areas where there is room for improvement. We’ve pulled out some interesting metrics below.
For reference, Github and Bugzilla measure developer contributions. TopicBox measures activity across our many mailing lists. Pontoon measures the activity from volunteers who help us translate and localize Thunderbird. SUMO measures the impact of Thunderbird’s support volunteers who engage with our users and respond to their varied support questions.
Contributor & Community Growth
Thank You
In conclusion, we’d simply like to thank this amazing community of Thunderbird supporters who give of their time and resources to create something great. 2023 and 2024 have been years of extraordinary improvement for Thunderbird and the future looks bright. We’re humbled and pleased that so many of you share our values of privacy, digital wellbeing and open standards. We’re committed to continuing to provide Thunderbird for free to everyone, everywhere – thanks to you!

Just to provide another perspective: if you can write the programs you want to write, then all is good. You don't have to use every single tool in the standard library.
I co-authored the Rust book. I have twelve years experience writing Rust code, and just over thirty years of experience writing software. I have written a macro_rules macro exactly one time, and that was 95% taking someone else's macro and modifying it. I have written one proc macro. I have used Box::leak once. I have never used Arc::downgrade. I've used Cow a handful of times.
WebDriver is a remote control interface that enables introspection and control of user agents.As such itcanhelp developers to verify that their websites are working and performing well with all major browsers. The protocol is standardized by the W3C and consists of two separate specifications: WebDriver classic (HTTP) and the new WebDriver BiDi (Bi-Directional).
This newsletter gives an overview of the work we’ve done as part of the Firefox 131 release cycle.
Contributions
Firefox – including our WebDriver implementation – is developed as an open source project, and everyone is welcome to contribute. If you ever wanted to contribute to an open source project used by millions of users, or are interested in some experience in software development, jump in.
We are always grateful to receive external contributions, here are the ones which made it in Firefox 131:
New: Add support for remaining arguments of “network.continueResponse”
In Firefox 131 we added support for the remaining arguments of the "network.continueResponse" command, such as cookies, headers, statusCode and reasonPhrase. This allows clients to modify cookies, headers, status codes (e.g., 200, 304), and status text (e.g., “OK”, “Not modified”) during the "responseStarted" phase, when a real network response is intercepted, while preserving the response body.
Transparency note: According to Colibri Hero, they attempted to establish a business relationship with eyeo, a company that I co-founded. I haven’t been in an active role at eyeo since 2018, and I left the company entirely in 2021. Colibri Hero was only founded in 2021. My investigation here was prompted by a blog comment.
Colibri Hero (also known as allcolibri) is a company with a noble mission:
We want to create a world where organizations can make a positive impact on people and communities.
One of the company’s products is the refoorest browser extension, promising to make a positive impact on the climate by planting trees. Best of it: this costs users nothing whatsoever. According to the refoorest website:
Plantation financed by our partners
So the users merely need to have the extension installed, indicating that they want to make a positive impact. And since the concept was so successful, Colibri Hero recently turned it into an SDK called Impact Hero (also known as Impact Bro), so that it could be added to other browser extensions.
What the company carefully avoids mentioning: its 56,000 “partners” aren’t actually aware that they are financing tree planting. The refoorest extension and extensions using the Impact Hero SDK automatically open so-called affiliate links in the browser, making certain that the vendor pays them an affiliate commission for whatever purchases the users make. As the extensions do nothing to lead users to a vendor’s offers, this functionality likely counts as affiliate fraud.
The refoorest extension also makes very clear promises to its users: planting a tree for each extension installation, two trees for an extension review as well as a tree for each vendor visit. Clearly, this is not actually happening according to the numbers published by Colibri Hero themselves.
What does happen is careless handling of users’ data despite the “100% Data privacy guaranteed” promise. In fact, the company didn’t even bother to produce a proper privacy policy. There are various shady practices including a general lack of transparency, with the financials never disclosed. As proof of trees being planted the company links to a “certificate” which is … surprise! … its own website.
Mind you, I’m not saying that the company is just pocketing the money it receives via affiliate commissions. Maybe they are really paying Eden Reforestation (not actually called that any more) to plant trees and the numbers they publish are accurate. As a user, this is quite a leap of faith with a company that shows little commitment to facts and transparency however.
Contents
What is Colibri Hero?
Let’s get our facts straight. First of all, what is Colibri Hero about? To quote their mission statement:
Because more and more companies are getting involved in social and environmental causes, we have created a SaaS solution that helps brands and organizations bring impactful change to the environment and communities in need, with easy access to data and results. More than that, our technology connects companies and non-profit organizations together to generate real impact.
Our e-solution brings something new to the demand for corporate social responsibility: brands and organizations can now offer their customers and employees the chance to make a tangible impact, for free. An innovative way to create an engaged community that feels empowered and rewarded.
You don’t get it? Yes, it took me a while to understand as well.
This is about companies’ bonus programs. Like: you make a purchase, you get ten points for the company’s loyalty program. Once you have a few hundred of those points, you can convert them into something tangible: getting some product for free or at a discount.
And Colibri Hero’s offer is: the company can offer people to donate those points, for a good cause. Like planting trees or giving out free meals or removing waste from the oceans. It’s a win-win situation: people can feel good about themselves, the company saves themselves some effort and Colibri Hero receives money that they can forward to social projects (after collecting their commission of course).
I don’t know whether the partners get any proof of money being donated other than the overview on the Colibri Hero website. At least I could not find any independent confirmation of it happening. All photos published by the company are generic and from unrelated events. Except one: there is photographic proof that some notebooks (as in: paper that you write on) have been distributed to girls in Sierra Leone.
Few Colibri Hero partners report the impact of this partnership or even its existence. The numbers are public on Colibri Hero website however if you know where to look for them and who those partners are. And since Colibri Hero left the directory index enabled for their Google Storage bucket, the logos of their partners are public as well.
So while Colibri Hero never published a transparency report themselves, it’s clear that they partnered up with less than 400 companies. Most of these partnerships appear to have never gone beyond a trial, the impact numbers are negligible. And despite Colibri Hero boasting their partnerships with big names like Decathlon and Foot Locker, the corresponding numbers are rather underwhelming for the size of these businesses.
Colibri Hero runs a shop which they don’t seem to link anywhere but which gives a rough impression of what they charge their partners. Combined with the public impact numbers (mind you, these have been going since the company was founded in 2021), this impression condenses into revenue numbers far too low to support a company employing six people in France, not counting board members and ethics advisors.
And what about refoorest?
This is likely where the refoorest extension comes in. While given the company’s mission statement this browser extension with its less than 100,000 users across all platforms (most of them on Microsoft Edge) sounds like a side hustle, it should actually be the company’s main source of income.
The extension’s promise sounds very much like that of the Ecosia search engine: you search the web, we plant trees. Except that with Ecosia you have to use their search engine while refoorest supports any search engine (as well as Linkedin and Twitter/X which they don’t mention explicitly). Suppose you are searching for a new pair of pants on Google. One of the search results is Amazon. With refoorest you see this:
If you click the search result you go to Amazon as usual. Clicking that added link above the search result however will send you to the refoorest.com domain, where you will be redirected to the v2i8b.com domain (an affiliate network) which will in turn redirect you to amazon.com (the main page, not the pants one). And your reward for that effort? One more tree added to your refoorest account! Planting trees is really easy, right?
One thing is odd about this extension’s listing on Chrome Web Store: for an extension with merely 20,000 users, 2.9K ratings is a lot.
One reason is: the extension incentivizes leaving reviews. This is what the extension’s pop-up looks like:
Review us and we will plant two trees! Give us your email address and we will plant another two trees! Invite fifteen friends and we will plant a whole forest for you!
The newcomer: Impact Hero
Given the success of refoorest, it’s unsurprising that the company is looking for ways to expand this line of business. What they recently came up with is the Impact Hero SDK, or Impact Bro as its website calls it (yes, really). It adds an “eco-friendly mode” to existing extensions. To explain it with the words of the Impact Bros (highlighting of original):
With our eco-friendly mode, you can effortlessly plant trees and offset carbon emissions at no cost as you browse the web. This allows us to improve the environmental friendliness of our extension.
Wow, that’s quite something, right? And how is that possible? That’s explained a little further in the text:
Upon visiting one of these merchant partners, you’ll observe a brief opening of a new tab. This tab facilitates the calculation of the required carbon offset.
Oh, calculation of the required carbon offset, makes sense. That’s why it loads the same website that I’m visiting but via an affiliate network. Definitely not to collect an affiliate commission for my purchases.
Just to make it very clear: the thing about calculating carbon offsets is a bold lie. This SDK earns money via affiliate commissions, very much in the same way as the refoorest extension. But rather than limiting itself to search results and users’ explicit clicks on their link, it will do this whenever the user visits some merchant website.
All functionalities of extensions should be clearly disclosed to the user, with no surprises.
Good that the Impact Hero SDK includes a consent screen, right? Here is what it looks like in the Chat GPT extension:
Yes, this doesn’t really help users make an informed decision. And if you think that the “Learn more” link helps, it leads to the page where I copied the “calculation of the required carbon offset” bullshit from.
The whole point of this “consent screen” seems to be tricking you into granting the extension access to all websites. Consequently, this consent screen is missing from extensions that already have access to all websites out of the box (including the two extensions owned by Colibri Hero themselves).
There is one more area that Colibri Hero focuses on to improve its revenue: their list of merchants that the extensions download each hour. This discussion puts the size of the list at 50 MB on September 6. When I downloaded it on September 17 it was already 62 MB big. By September 28 the list has grown to 92 MB. If this size surprises you: there are lots of duplicate entries. amazon.com alone is present 615 times in that list (some metadata differs, but the extensions don’t process that metadata anyway).
Affected extensions
In addition to refoorest I could identify two extensions bought by Colibri Hero from their original author as well as 14 extensions which apparently added Impact Hero SDK expecting their share of the revenue. That’s Chrome Web Store only, the refoorest extension at the very least also exists in various other extension stores, even though it has been removed from Firefox Add-ons just recently.
Here is the list of extensions I found and their current Chrome Web Store stats:

Edit (2024-10-01): Opera already removed refoorest from their add-on store.
But are they actually planting trees?
That’s a very interesting question, glad you asked. See, refoorest considers itself to be in direct competition with the Ecosia search engine. And Ecosia publishes detailed financial reports where they explain how much money they earn and where it went. Ecosia is also listed as a partner on the Eden: People+Planet website, so we have independent confirmation here that they in fact donated at least a million US dollars.
I searched quite thoroughly for comparable information on Colibri Hero. All I could find was this statement:
We allocate a portion of our income to operating expenses, including team salaries, social charges, freelancer payments, and various fees (such as servers, technical services, placement fees, and rent). Additionally, funds are used for communications to maximize the service’s impact.
Then, 80% of the profits are donated to global reforestation projects through our partner, Eden Reforestation.
While this sounds good in principle, we have no idea how high their operational expenses are. Maybe they are donating half of their revenue, maybe none. Even if this 80% rule is really followed, it’s easy to make operational expenses (like the salary of the company founders) so high that there is simply no profit left.
Edit (2024-10-01): It seems that I overlooked them in the list of partners. So they did in fact donate at least 50 thousand US dollars. Thanks to Adrien de Malherbe of Colibri Hero for pointing this out. Edit (2024-10-02): According to the Internet Archive, refoorest got listed here in May 2023 and they have been in the “$50,000 - $99,999” category ever since. They were never listed with a smaller donation, and they never moved up either – almost like this was a one-time donation. As of October 2024, the Eden: People+Planet website puts the cost of planting a tree at $0.75.
And other than that they link to the certificate of the number of trees planted:
But that’s their own website, just like the maps of where trees are being planted. They can make it display any number.
Now you are probably thinking: “Wladimir, why are you so paranoid? You have no proof that they are lying, just trust them to do the right thing. It’s for a good cause!” Well, actually…
Remember that the refoorest extension promises its users to plant a specific number of trees? One for each extension installation, two for a review, one more tree each time a merchant website is visited? What do you think, how many trees came together this way?
One thing about Colibri Hero is: they don’t seem to be very fond of protecting data access. Not only their partners’ stats are public, the user data is as well. When the extension loads or updates the user’s data, there is no authentication whatsoever. Anybody can just open my account’s data in their browser provided that they know my user ID:
So anybody can track my progress – how many trees I’ve got, when the extension last updated my data, that kind of thing. Any stalkers around? Older data (prior to May 2022) even has an email field, though this one was empty for the accounts I saw.
How you might get my user ID? Well, when the extension asks me to promote it on social networks and to my friends, these links contain my user ID. There are plenty of such links floating around. But as long as you aren’t interested in a specific user: the user IDs are incremental. They are even called row_index in the extension source code.
See that index value in my data? We now know that 2,834,418 refoorest accounts were created before I decided to take a look. Some of these accounts certainly didn’t live long, yet the average still seems to be beyond 10 trees. But even ignoring that: two million accounts are two million trees just for the install.
According to their own numbers refoorest planted less that 700,000 trees, far less than those accounts “earned.” In other words: when these users were promised real physical trees, that was a lie. They earned virtual points to make them feel good, when the actual count of trees planted was determined by the volume of affiliate commissions.
Wait, was it actually determined by the affiliate commissions? We can get an idea by looking at the historical data for the number of planted trees. While Colibri Hero doesn’t provide that history, the refoorest website was captured by the Internet Archive at a significant number of points in time. I’ve collected the numbers and plotted them against the respective date. Nothing fancy like line smoothing, merely lines connecting the dots:
Well, that’s a straight line. There is a constant increase rate of around 20 trees per hour here. And I hate to break it to you, a graph like that is rather unlikely to depend on anything related to the extension which certainly grew its user base over the course of these four years.
There are only two anomalies here where the numbers changed non-linearly. There is a small jump end of January or start of February 2023. And there is a far larger jump later in 2023 after a three month period where the Internet Archive didn’t capture any website snapshots, probably because the website was inaccessible. When it did capture the number again it was already above 500,000.
The privacy commitment
Refoorest website promises:
100% Data privacy guaranteed
The Impact Hero SDK explainer promises:
This new feature does not retain any information or data, ensuring 100% compliance with GDPR laws.
Ok, let’s first take a look at their respective privacy policies. Here is the refoorest privacy policy:
If you find that a little bit hard to read, that’s because whoever copied that text didn’t bother to format lists and such. Maybe better to read it on the Impact Bro website?
Sorry, that’s even worse. Not even the headings are formatted here.
Either way, nothing shows appreciation for privacy like a standard text which is also used by pizza restaurants and similarly caring companies. Note how that references “Law No. 78-17 of 6 January 1978”? That’s some French data protection law that I’m pretty certain is superseded by GDPR. A reminder: GDPR came in effect in 2018, three years before Colibri Hero was even founded.
This privacy policy isn’t GDPR-compliant either. For example, it has no mention of consumer rights or who to contact if I want my data to be removed.
Data like what’s stored in those refoorest accounts which happen to be publicly visible. Some refoorest users might actually find that fact unexpected.
Or data like the email address that the extension promises two trees for. Wait, they don’t actually have that one. The email address goes straight to Poptin LTD, a company registered in Israel. There is no verification that the user owns the address like double opt-in. But at least Poptin has a proper GDPR-compliant privacy policy.
There is plenty of tracking going on all around refoorest, with data being collected by Cloudflare, Google, Facebook and others. This should normally be explained in the privacy policy. Well, not in this one.
Granted, there is less tracking around the Impact Hero SDK, still a far shot away from the “not retain any information or data” promise however. The “eco-friendly mode” explainer loads Google Tag Manager. The affiliate networks that extensions trigger automatically collect data, likely creating profiles of your browsing. And finally: why is each request going through a Colibri Hero website before redirecting to the affiliate network if no data is being collected there?
Happy users
We’ve already seen that a fair amount of users leaving a review for the refoorest extension have been incentivized to do so. That’s the reason for “insightful” reviews like this one:
Funny enough, several of them then complain about not receiving their promised trees. That’s due to an extension issue: the extension doesn’t actually track whether somebody writes a review, it simply adds two trees with a delay after the “Leave a review” button is clicked. A bug in the code makes it “forget” that it meant to do this if something else happens in between. Rather that fixing the bug they removed the delay in the current extension version. The issue is still present when you give them your email address though.
But what about the user testimonies on their webpage?
Yes, this sounds totally like something real users would say, definitely not written by a marketing person. And these user photos definitely don’t come from something like the Random User Generator. Oh wait, they do.
In that context it makes sense that one of the company’s founders engages with the users in a blog titled “Eco-Friendly Living” where he posts daily articles with weird ChatGPT-generated images. According to metadata, all articles have been created on the same date, and each article took around four minutes – he must be a very fast typer. Every article presents a bunch of brands, and the only thing (currently) missing to make the picture complete are affiliate links.
Security issue
It’s not like the refoorest extension or the SDK do much. Given that, the company managed to produce a rather remarkable security issue. Remember that their links always point to a Colibri Hero website first, only to be redirected to the affiliate network then? Well, for some reason they thought that performing this redirect in the extension was a good idea.
So their extension and their SDK do the following:
Found a partnerurl parameter in the query string? Redirect to it! You wonder what websites this code is active on? All of them of course! What could possibly go wrong…
Well, the most obvious thing to go wrong is: this might be a javascript: URL. A malicious website could open https://example.com/?partnerurl=javascript:alert(1) and the extension will happily navigate to that URL. This almost became a Universal Cross-Site Scripting (UXSS) vulnerability. Luckily, the browser prevents this JavaScript code from running, at least with Manifest V3.
It’s likely that the same vulnerability already existed in the refoorest extension back when it was using Manifest V2. At that point it was a critical issue. It’s only with the improvements in Manifest V3 that extensions’ content scripts are subject to a Content Security Policy which prevents execution of arbitrary Javascript code.
So now this is merely an open redirect vulnerability. It could be abused for example to disguise link targets and abuse trust relationships. A link like https://example.com/?partnerurl=https://evil.example.net/ looks like it would lead to a trusted example.com website. Yet the extension would redirect it to the malicious evil.example.net website instead.
Conclusions
We’ve seen that Colibri Hero is systematically misleading extension users about the nature of its business. Users are supposed to feel good about doing something for the planet, and the entire communication suggests that the “partners” are contributing finances due to sharing this goal. The aspect of (ab)using the system of affiliate marketing is never disclosed.
This is especially damning in case of the refoorest extension where users are being incentivized by a number of trees supposedly planted as a result of their actions. At no point does Colibri Hero disclose that this number is purely virtual, with the actual count of trees planted being far lower and depending on entirely different factors. Or rather no factors at all if their reported numbers are to be trusted, with the count of planted trees always increasing at a constant rate.
For the Impact Hero SDK this misleading communication is paired with clearly insufficient user consent. Most extensions don’t ask for user consent at all, and those that do aren’t allowing an informed decision. The consent screen is merely a pretense to trick the users into granting extended permissions.
This by itself is already in gross violation of the Chrome Web Store policies and warrants a takedown action. Other add-on stores have similar rules, and Mozilla in fact already removed the refoorest extension prior to my investigation.
Colibri Hero additionally shows a pattern of shady behavior, such as quoting fake user testimonies, referring to themselves as “proof” of their beneficial activity and a general lack of transparency about finances. None of this is proof that this company isn’t donating money as it claims to do, but it certainly doesn’t help trusting them with it.
The technical issues and neglect for users’ privacy are merely a sideshow here. These are somewhat to be expected for a small company with limited financing. Even a small company can do better however if the priorities are aligned.

Tantek Çelik suggests that Creative Commons should add a CC-NT license, like the existing Creative Commons licenses, but written to make it clear that the content is not licensed for generative AI training. Manton Reece likes the idea, and would allow training—but understands why publishers would choose not to. AI training permissions are becoming a huge deal, and there is a need for more licensing options. disclaimer: we’re taking steps in this area at work now. This is a personal blog post though, not speaking for employer or anyone else. In the 2024 AI Training Survey Results from Draft2Digital, only 5% of the authors surveyed said that scraping and training without a license is fair use.
Arguably, copyright is not the right framework for defining the rules of this newly formed ecosystem.
That might be a good point from the legal scholarship point of view, but the frequently expressed point of view of web people is more like, creepy bots are scraping my stuff, I’ll throw anything at them I can to get them to stop.Cloudflare’s one-click AI scraper blocker is catching on. For a lot of the web, the AI problem feels more like an emergency looting situation than an academic debate. AI training permissions will be a point where people just end up disagreeing, and where the Creative Commons approach to copyright, where the license deliberately limits the rights that a content creator can try to assert, is a bad fit for what many web people really want. People disagree on what is and isn’t fair use, and how far the power of copyright law should extend. And some free culture people who would prefer less powerful copyright laws in principle are not inclined to unilaterally refuse to use a tool that others are already using.
The techbro definition of fair use (what’s yours is open, what’s mine is proprietary) is clearly bogus, so we can safely ignore that—but it seems like Internet freedom people can be found along both axes of the fair use alignment chart. yes, there are four factors, but generative AI typically uses the entire work, so we can ignore the amount one, and we’re generally talking about human-created personal cultural works, so the nature of the copyrighted works we’re arguing about is generally similar. So we’re down to two, which is good because I don’t know how to make 3 and 4d tables in HTML.
Transformative purist: work must be signficantly transformed
Transformative neutral: work must be somehow transformed
Transformative chaotic: work may be transformed
Market purist: work must not have a negative effect on the market for the original
Memes are fair use
AI business presentation assistants are fair use
A verbatim quotation from a book in a book review is fair use
Market neutral: work may have some effect on the market
We’re probably going to end up with alternate free culture licenses, which is a good thing. But it’s probably not realistic to get organizations to change their alignment too much. Free culture licensing is too good of an idea to keep with one licensing organization, just like free software foundations (lower case) are useful enough that it’s a good idea to have a redundant array of them.
Do we need a toothier, more practical license?
This site is not licensed under a Creative Commons license, because I have some practical requirements that aren’t in one of the standard CC licenses. These probably apply to more sites than just this one. Personally, I would be happier with a toothier license that covers some of the reasons I don’t use CC now.
No permission for generative AI training (already covered this)
Licensee must preserve links when using my work in a medium where links work. I’m especially interested in preserving link rel=author and link rel=canonical. I would not mind giving general permission for copying and mirroring material from this site, except that SEO is a thing. Without some search engine signal, it would be too easy for a copy of my stuff on a higher-ranked site to make this site un-findable. I’m prepared to give up some search engine juice for giving out some material, just don’t want to get clobbered wholesale.
Patent license: similar to open-source software license terms. You can read my site but not use it for patent trolling. If you use my content, I get a license to any of your patents that would be infringed by making the content and operating the site.
Privacy flags: this site is licensed for human use, not for sale or sharing of personal info for behavioral targeting. I object to processing of any personal information that may be collected or inferred from this site.
In general, if I can’t pick a license that lets me make content available to people doing normal people stuff, but not to non-human entities with non-human goals, I will have to make the people ask me in person. Putting a page on the web can have interesting consequences, and a web-aware license that works for me will probably needs to color outside the lines of the ideal copyright law that would make sense if we were coming up with copyright laws from scratch.

What would you say if I told you that it was possible to (a) eliminate a lot of “inter-method borrow conflicts” without introducing something like view types and (b) make pinning easier even than boats’s pinned places proposal, all without needing pinned fields or even a pinned keyword? You’d probably say “Sounds great… what’s the catch?” The catch it requires us to change Rust’s fundamental assumption that, given x: &mut T, you can always overwrite *x by doing *x = /* new value */, for any type T: Sized. This kind of change is tricky, but not impossible, to do over an edition.
TL;DR
We can reduce inter-procedural borrow check errors, increase clarity, and make pin vastly simpler to work with if we limit when it is possible to overwrite an &mut reference. The idea is that if you have a mutable reference x: &mut T, it should only be possible to overwrite x via *x = /* new value */ or to swap its value via std::mem::swap if T: Overwrite. To start with, most structs and enums would implement Overwrite, and it would be a default bound, like Sized; but we would transition in a future edition to have structs/enums be !Overwrite by default and to have T: Overwrite bounds written explicitly.
Structure of this series
This blog post is part of a series:
This first post will introduce the idea of immutable fields and show why they could make Rust more ergonomic and more consistent. It will then show how overwrites and swaps are the key blocker and introduce the idea of the Overwrite trait, which could overcome that.
In the next post, I’ll dive deeper into Pin and how the Overwrite trait can help there.
After that, who knows? Depends on what people say in response.1
If you could change one thing about Rust, what would it be?
People often ask me to name something I would change about Rust if I could. One of the items on my list is the fact that, given a mutable reference x: &mut SomeStruct to some struct, I can overwrite the entire value of x by doing *x = /* new value */, versus only modifying individual fields like x.field = /* new value */.
Having the ability to overwrite *x always seemed very natural to me, having come from C, and it’s definitely useful sometimes (particularly with Copy types like integers or newtyped integers). But it turns out to make borrowing and pinning much more painful than they would otherwise have to be, as I’ll explain shortly.
In the past, when I’ve thought about how to fix this, I always assumed we would need a new form of reference type, like &move T or something. That seemed like a non-starter to me. But at RustConf last week, while talking about the ergonomics of Pin, a few of us stumbled on the idea of using a trait instead. Under this design, you can always make an x: &mut T, but you can’t always assign to *x as a result. This turns out to be a much smoother integration. And, as I’ll show, it doesn’t really give up any expressiveness.
Motivating example #1: Immutable fields
In this post, I’m going to motivate the changes by talking about immutable fields. Today in Rust, when you declare a local variable let x = …, that variable is immutable by default2. Fields, in contrast, inherit their mutability from the outside: when a struct appears in a mut location, all of its fields are mutable.
Not all fields are mutable, but I can’t declare that in my Rust code
It turns out that declaring local variables as mut is not needed for the borrow checker — and yet we do it nonetheless, in part because it helps readability. It’s useful to see when a variable might change. But if that argument holds for local variables, it holds double for fields! For local variables, we can find all potential mutation just by searching one function. To know if a field may be mutated, we have to search across many functions. And for fields, precisely because they can be mutated across functions, declaring them as immutable can actually help the borrow checker to see that your code is safe.
Idea: Declare fields as mutable
So what if we extended the mutable declaration to fields? The idea would be that, in your struct, if you want to mutate fields, you have to declare them as mut. This would allow them to be mutated: but only if the struct itself appears in a mutable local field.
For example, maybe I have an Analyzer struct that is created with some vector of datums and which has to compute the number of “important” ones:
#[derive(Default)]structAnalyzer{/// Data being analyzed: will never be modified.
data: Vec<Datum>,/// Number of important datums uncovered so far.
mutimportant: usize,}
As you can see from the struct declaration, the field data is declared as immutable. This is because we are only going to be reading the Datum values. The important
field is declared as mut, indicating that it will be updated.
When can you mutate fields?
In this world, mutating a field is only possible when (1) the struct appears in a mutable location and (2) the field you are referencing is declared as mut. So this code compiles fine, because the field important is mut:
letmutanalyzer=Analyzer::new();analyzer.important+=1;// OK: mut field in a mut location
But this code does not compile, because the local variable x is not:
letx=Analyzer::default();x.important+=1;// ERROR: `x` not declared as mutable
And this code does not compile, because the field data is not declared as mut:
letmutx=Analyzer::default();x.data.clear();// ERROR: field `data` is not declared as mutable
Leveraging immutable fields in the borrow checker
So why is it useful to declare fields as mut? Well, imagine you have a method like increment_if_important, which checks if datum.is_important() is true and modifies the important flag if so:
I can hear the experienced Rustaceans crying out in pain now. This function, natural as it appears, will not compile in Rust today. Why is that? Well, we have a shared borrow on self.data but we are trying to call an &mut self function, so we have no way to be sure that self.data will not be modified.
But what about immutable fields? Doesn’t that solve this?
Annoyingly, immutable fields on their own don’t change anything! Why? Well, just because you can’t write to a field directly doesn’t mean you can’t mutate the memory it’s stored in. For example, maybe I write a malicious version of increment_if_important:
This version never directly accesses the field data, but it just writes to *self, and hence it has the same impact. Annoying!
Generics: why we can’t trivially disallow overwrites
Maybe you’re thinking “well, can’t we just disallow overwriting *self if there are fields declared mut?” The answer is yes, we can, and that’s what this blog post is about. But it’s not so simple as it sounds, because we are changing the “basic contract” that all Rust types currently satisfy. In particular, Rust today assumes that if you have a reference x: &mut T and a value v: T, you can always do *x = v and overwrite the referent of x. That means I could can write a generic function like set_to_default:
Now, since Analyzer implements Default, I can make increment_if_important call set_to_default. This will still free self.data, but it does it in a sneaky way, where we can’t obviously tell that the value being overwritten is an instance of a struct with mut fields:
implAnalyzer{fnmalicious_increment_if_important(&mutself,datum: &Datum){// Overwrites `self.data`, but not in an obvious way
set_to_default(self);}}
Recap
So let’s step back and recap what we’ve seen so far:
If we could distinguish which fields were mutable and which were definitely not, we could eliminate many inter-function borrow check errors3.
However, just adding mut declarations is not enough, because fields can also be mutated indirectly. Specifically, when you have a &mut SomeStruct, you can overwrite with a fresh instance of SomeStruct or swap with another &mut SomeStruct, thus changing all fields at once.
Whatever fix we use has to consider generic code like std::mem::swap, which mutates an &mut T without knowing precisely what T is. Therefore we can’t do something simple like looking to see if T is a struct with mut fields4.
The trait system to the rescue
My proposal is to introduce a new, built-in marker trait called Overwrite:
/// Marker trait that permits overwriting
/// the referent of an `&mut Self` reference.
#[marker]// <-- means the trait cannot have methods
traitOverwrite: Sized{}
The effect of Overwrite
As a marker trait, Overwrite does not have methods, but rather indicates a property of the type. Specifically, assigning to a borrowed place of type T requires that T: Overwrite is implemented. For example, the following code writes to *x, which has type T; this is only legal if T: Overwrite:
Given this this code compiles today, this implies that a generic type parameter declaration like <T> would require a default Overwrite bound in the current edition. We would want to phase these defaults out in some future edition, as I’ll describe in detail later on.
Similarly, the standard library’s swap function would require a T: Overwrite bound, since it (via unsafe code) assigns to *x and *y:
The Overwrite trait requires Sized because, for *x = /* new value */ to be safe, the compiler needs to ensure that the place *x has enough space to store “new value”, and that is only possible when the size of the new value is known at compilation time (i.e., the type implements Sized).
Overwrite only applies to borrowed values
The overwrite trait is only needed when assigning to a borrowed place of type T. If that place is owned, the owner is allowed to reassign it, just as they are allowed to drop it. So e.g. the following code compiles whether or not SomeType: Overwrite holds:
letmutx: SomeType=/* something */;x=/* something else */;// <— does not require that `SomeType: Overwrite` holds
Subtle: Overwrite is not infectious
Somewhat surprisingly, it is ok to have a struct that implements Overwrite which has fields that do not. Consider the types Foo and Bar, where Foo: Overwrite holds but Bar: Overwrite does not:
letfoo=&mutFoo(Bar);// OK: Overwriting a borrowed place of type `Foo`
// and `Foo: Overwrite` holds.
*foo=Foo(Bar);
However, the following code would not:
letfoo=&mutFoo(Bar);// ERROR: Overwriting a borrowed place of type `Bar`
// but `Bar: Overwrite` does not hold.
foo.0=Bar;
Types that do not implement Overwrite can therefore still be overwritten in memory, but only as part of overwriting the value in which they are embedded. In the FAQ I show how this non-infectious property preserves expressiveness.5
Who implements Overwrite?
This section walks through which types should implement Overwrite.
Copy implies Overwrite
Any type that implements Copy would automatically implement Overwrite:
impl<T: Copy>OverwriteforT{}
(If you, like me, get nervous when you see blanket impls due to coherence concerns, it’s worth noting that RFC #1268 allows for overlapping impls of marker traits, though that RFC is not yet fully implemented nor stable. It’s not terribly relevant at the moment anyway.)
“Pointer” types are Overwrite
Types that represent pointers all implement Overwrite for all T:
&T
&mut T
Box<T>
Rc<T>
Arc<T>
*const T
*mut T
dyn,[], and other “unsized” types do not implement Overwrite
Types that do not have a static size, like dyn and [], do not implement Overwrite. Safe Rust already disallows writing code like *x = … in such cases.
There are ways to do overwrites with unsized types in unsafe code, but they’d have to prove various bounds. For example, overwriting a [u32] value could be ok, but you have to know the length of data. Similarly swapping two dyn Value referents can be safe, but you have to know that (a) both dyn values have the same underlying type and (b) that type implements Overwrite.
Structs and enums
The question of whether structs and enums should implement Overwrite is complicated because of backwards compatibility. I’m going to distinguish two cases: Rust 2021, and Rust Next, which is Rust in some hypothetical future edition (surely not 2024, but maybe the one after that).
Rust 2021. Struct and enum types in Rust 2021 implement Overwrite by default. Structs could opt-out from Overwrite with an explicit negative impl (impl !Overwrite for S).
Integrating mut fields. Structs that have opted out from Overwrite require mutable fields to be declared as mut. Fields not declared as mut are immutable. This gives them the nicer borrow check behavior.6
Rust Next. In some future edition, we can swap the default, with fields being !Overwrite by default and having to opt-in to enable overwrites. This would make the nice borrow check behavior the default.
Futures and closures
Futures and closures can implement Overwrite iff their captured values implement Overwrite, though in future editions it would be best if they simple do not implement Overwrite.
Default bounds and backwards compatibility
The other big backwards compatibility issue has to do with default bounds. In Rust 2021, every type parameter declared as T implicitly gets a T: Sized bound. We would have to extend that default to be T: Sized + Overwrite. This also applies to associated types in trait definitions and impl X types.7
Interestingly, type parameters declared as T: ?Sizedalso opt-out from Overwrite. Why is that? Well, remember that Overwrite: Sized, so if T is not known to be Sized, it cannot be known to be Overwrite either. This is actually a big win. It means that types like &T and Box<T> can work with “non-overwrite” types out of the box.
Associated type bounds are annoying, but perhaps not fatal
Still, the fact that default bounds apply to associated types and impl Trait is a pain in the neck. For example, it implies that Iterator::Item would require its items to be Overwrite, which would prevent you from authoring iterators that iterate over structs with immutable fields. This can to some extent be overcome by associated type aliases8 (we could declare Item to be a “virtual associated type”, mapping to Item2021 in older editions, which require Overwrite, and ItemNext in newer ones, which do not).
Frequently asked questions
OMG endless words. What did I just read?
Let me recap!
It would be more declarative and create fewer borrow check conflicts if we had users declare their fields as mut when they may be mutated and we were able to assume that non-mut fields will never be mutated.
If we were to add this, in the current Rust edition it would obviously be opt-in.
But in a future Rust edition it would become mandatory to declare fields as mut if you want to mutate them.
But to do that, we need to prevent overwrites and swaps. We can do that by introducing a trait, Overwrite, that is required to a given location.
In the current Rust edition, this trait would be added by default to all type parameters, associated types, and impl Trait bounds; it would be implemented by all structs, enums, and unions.
In a future Rust edition, the trait would no longer be the default, and structs, enums, and unions would have to explicitly implement if they want to be overwriteable.
This change doesn’t seem worth it just to get immutable fields. Is there more?
But wait, there’s more! Oh, you just said that. Yes, there’s more. I’m going to write a follow-up post showing how opting out from Overwrite eliminates most of the ergonomic pain of using Pin.
In “Rust Next”, who would ever implement Overwrite manually?
I said that, in Rust Next, types should be !Overwrite by default and require people to implement Overwrite manually if they want to. But who would ever do that? It’s a good question, because I don’t think there’s very much reason to.
Because Overwrite is not infectious, you can actually make a wrapper type…
…and now you can put values of any type X into an ForceOverwrite <X> which can be reassigned.
This pattern allows you to make “local” use of overwrite, for example to implement a sorting algorithm (which has to do a lot of swapping). You could have a sort function that takes an &mut [T] for any T: Ord (Overwrite not required):
fnsort<T: Ord>(data: &mut[T])
Internally, it can safely transmute the &mut [T] to a &mut [ForceOverwrite<T>] and sort that. Note that at no point during that sorting are we moving or overwriting an element while it is borrowed (the slice that owns it is borrowed, but not the elements themselves).
What is the relationship of Overwrite and Unpin?
I’m still puzzling that over myself. I think that Overwrite is “morally the same” as Unpin, but it is much more powerful (and ergonomic) because it is integrated into the behavior of &mut (of course, this comes at the cost of a complex backwards compatibility story).
Let me describe it this way. Types that do not implement Overwrite cannot be overwritten while borrowed, and hence are “pinned for the duration of the borrow”. This has always been true for &T, but for &mut T has traditionally not been true. We’ll see in the next post that Pin<&mut T> basically just extends that guarantee to apply indefinitely.
Compare that to types that do not implement Unpin and hence are “address sensitive”. Such types are pinned for the duration of a Pin<&mut T>. Unlike T: !Overwrite types, they are not pinned by &mut T references, but that’s a bug, not a feature: this is why Pin has to bend over backwards to prevent you from getting your hands on an &mut T.
I’ll explain this more in my next post, of course.
Should Overwrite be an auto trait?
I think not. If we did so, it would lock people into semver hazards in the “Rust Next” edition where mut is mandatory for mutation. Consider a struct Foo { value: u32 } type. This type has not opted into becoming Copy, but it only contains types that are Copy and therefore Overwrite. By auto trait rules it would by default be Overwrite. But that would prevent you from adding a mut field in the future or benefit from immutable fields. This is why I said the default would just be !Overwrite, no matter the field types.
Conclusion
=)
After this grandiose intro, hopefully I won’t be printing a retraction of the idea due to some glaring flaw… eep! ↩︎
Whenever I saw immutable here, I mean immutable-modulo-Cell, of course. We should probably find another word for that, this is kind of terminology debt that Rust has bought its way into and I’m not sure the best way for us to get out! ↩︎
Immutable fields don’t resolve all inter-function borrow conflicts. To do that, you need something like view types. But in my experience they would eliminate many. ↩︎
The simple solution — if a struct has mut fields, disallow overwriting it — is basically what C++ does with their const fields. Classes or structs with const fields are more limited in how you can use them. This works in C++ because they don’t wait until post-substitution to check templates for validity. ↩︎
I love the Felleisen definition of “expressiveness”: two language features are equally expressive if one can be converted into the other with only local rewrites, which I generally interpret as “rewrites that don’t affect the function signature (or other abstraction boundary)”. ↩︎
We can also make the !Overwrite impl implied by declaring fields mut, of course. This is fine for backwards compatibility, but isn’t the design I would want long-term, since it introduces an odd “step change” where declaring one field as mut implicitly declares all other fields as immutable (and, conversely, deleting the mut keyword from that field has the effect of declaring all fields, including that one, as mutable). ↩︎
The Self type in traits is exempt from the Sized default, and it could be exempt from the Overwrite default as well, unless the trait is declared as Sized. ↩︎
The wait is almost over! Thunderbird for Android will be here soon. As an open-source project, we could not succeed without the incredible volunteer contributors who help us along the way. Whether you’re a fan of problem-solving, localization, testing, development, or even just spreading the word, there’s a role for you in our community. Contributing doesn’t just benefit us – it’s a great way to grow your own skills and make a real difference in the lives of thousands of Thunderbird users worldwide. However you choose to contribute to Thunderbird for Android, we’re always happy to welcome new friends to the project!
Support
If you’re a natural at getting to the root of problems, consider becoming a support contributor!
When you answer a support question, you’re not only helping the person who asked the question, you’re helping the hundreds if not thousands of people who read it. Or if you like writing and editing, you can help with our knowledge base (KB) articles!
Support for Thunderbird on Android will live on Mozilla Support, aka SUMO, just like support for the Desktop application, but under its own product tile. We’ve put together a guide to get you started on SUMO, from setting up an account and finding questions to best practices, whether you to decide to help in the question forums or in the KB articles. Want to talk to other support volunteers? Join us on our Support Crew Matrix channel.
Localization
Thunderbird’s users are all over the world, and our localization contributors put the app and support articles in their language. Thunderbird for Android’s localization lives on Weblate, copyleft libre continuous localization that powers many other open source projects. If you haven’t used Weblate before, they have a useful guide for getting started.
Testing
If you want to try the newest features and help us polish and perfect them before they make it to a general release, join us as a tester. Testers are comfortable using daily and beta releases and providing meaningful feedback to developers.
When they’re available, you can download the Thunderbird for Android Beta releases from the Google Play Store or from GitHub under the ‘Pre-Release’. F-Droid users will need to manually select beta versions. To get update notification for non-suggested versions you need to check ‘Settings > Expert mode > Unstable updates’ in the F-Droid app.
Just like Thunderbird for desktop, we have a mailing list where you can give feedback and talk to developers and fellow beta testers.
Development
Interested at helping at the code level? All our development happens on our GitHub page, where you can read our code contributor section in our CONTRIBUTING.md page.
Look for issues that are tagged ‘good first issue,’ even if you’re an experienced developer but are new to Thunderbird for Android. Use the android-planning mailing list to talk to and get feedback from other developers.
Promote Thunderbird for Android
Spreading the word about Thunderbird for Android is an essential way to contribute, and there are many ways to do this. You can leave us a positive review on the Google Play Store (if you had a positive experience, of course) and encourage others to download and try Thunderbird for Android. This could be friends or family, a local computer club, or any other group you could think of! We’d love to hear your ideas and find a way to support you on the android-planning mailing list.
Financial Support
Financial support is a fantastic way to ensure the project continues to thrive. Your gift goes toward improving features, fixing bugs, and expanding the app’s functionality for all of its users.
By supporting Thunderbird financially, you’re investing in open-source software that respects your privacy and gives you control over your data. Every contribution, no matter how small, helps us maintain our independence and stay true to our mission.
In today’s edition of our Contributor Spotlight, I’m thrilled to introduce you to Noah Y, a longtime contributor to our community forums. Noah’s excellence lies in his eagle-eyed investigation, most recently demonstrated when he identified that NordVPN’s web protection feature was causing Firefox auto-updates to fail. Thanks to his thorough investigation, the issue was escalated, and the SUMO content team was able to create a troubleshooting article to address the issue. In the end, NordVPN was able to resolve the problem after one of our engineers filed a support ticket with their team.
… So the way I decide if it’s worth escalating is if it affects any major/popular service or website. Because then I know thousands & possibly millions of Firefox users could be hitting the same bug quietly becoming very angry or frustrated each time they run into the problem.
Q: Please tell us about yourself
I love troubleshooting tough problems. And I love working with tech. Computers, TVs, you name it. I would take apart any electronics just on a small hope I could fix them or at least clean out the tons of dust hiding in them. I’m always intrigued by cars, tech & software. Despite this big interest, I never pursued an engineering or computer science degree. Which leaves me wishing I knew how to code. But if I did, it might have become too much of an obsession since I would want to fix everything that annoys me in my favorite software. So I’m happy I didn’t go down that path.
Q: I believe you’ve been involved with Mozilla since SUMO started. Can you tell us more about how you started contributing and what motivates you to keep going until now?
That’s right. I did start way back in 2004 by testing Firefox Nightly builds on a very cool forum community called MozillaZine Forums. Everyone helped report bugs & issues that needed to be fixed. I was good at that. Seeing those bugs get fixed was very satisfying & motivating.
But I never provided true support on those forums, I just helped test & confirm other people’s bugs/issues. The community there was very engaging & still is to this day over 20 yrs later.
I think how I got started contributing to SUMO in 2008 when it first launched, was by just answering a few questions by chance & seeing what would happen. I think I also felt bad at the time there were so many questions being asked with only a few helpers. It looked overwhelming. I mostly remember a ton of questions about Firefox crashes & homepage/search engine hijacking by malware or bad add-ons.
Q: Can you describe your workflow when working on the forum?
I try to jump around in the forums looking for missed genuine questions where the user looks really troubled but also gives a sense that they will reply. Anyone who cares enough to reply back to us once we respond is always someone I’m very interested in helping. Depending on their skills, they can also report back to us what setting, add-on or 3rd party software broke Firefox for them. So that can help us solve many more questions about the same issue.
Q: Can you share your tips and tricks for handling a difficult user on the forum? What’s your advice for other community members to avoid being overwhelmed with so many things to do?
I would say try to relate to the angry user’s frustration & let them know you understand how bad/annoying of a situation this is. I usually make it a point to let them know of past & recent issues where a website, add-on, or 3rd party software broke Firefox & that it’s not always Firefox’s fault when something breaks. There is a perception out there that every annoying issue is caused by Firefox itself or a Firefox update. This doesn’t calm down every angry user but for the reasonable users, they now understand that the blame is either shared or coming from the other side entirely.
For overwhelmed forum helpers, my advice is to reduce how many questions you respond to. I’m always surprised by how many new questions are posted daily & how I realize that not all of them are going to get solved. With that understanding, I have made my peace with only helping as many people as I can without feeling like I’m going to burnout.
Q: You have a knack in noticing a trending topic on the forum. Do you have a specific way to keep track of issues and how can you tell if an issue is worth escalating?
Thank you! I wasn’t sure if anyone else noticed that. It’s a blessing & a curse. Because once I discover a trending topic like that, I keep collecting as much info as possible & keep drilling into the details until I unlock a clue. And I won’t stop until we solve it or it’s ruled so hopeless that no one can fix it. It’s honestly like detective work.
I try to keep notes & a list of all the questions encountering the trending issue in a basic text document. Pretty old school. I may need a cooler tool to help organize & visualize this data. :) And as I keep tracking the issue & noticing more & more people appearing with the same issue, it becomes personal for me.
Because I used to be that user, suffering from some insane problem that was driving me crazy and it disrupted my work or enjoyment of the internet and absolutely nothing would solve it. When a problem becomes that severe, I realized that no one’s going to do anything about it until you start making a lot of noise & sounding the alarm bells & contacting the right people in power to help confirm, prioritize and get as many staff needed to get it fixed. Which by the way, is very awesome. As you can not easily escalate issues like this in other companies unless you are a staff member. Even then, the issue can still fall through the cracks unless you reach exactly the right person.
So the way I decide if it’s worth escalating is if it affects any major/popular service or website. Because then I know thousands & possibly millions of Firefox users could be hitting the same bug quietly becoming very angry or frustrated each time they run into the problem. Eventually they’ll become fatigued & come to the SUMO forums to vent about it or plead their desperation for getting it fixed as its ruining their lives in a lot of important areas (Can’t login to bank site, can’t watch movie/tv shows, can’t pay bills, can’t login to webmail, can’t access Medicare/Social security site, etc.). I try to proactively hunt these issues down before they become major trends. :)
Q: Given your experience, can you mention one or two things that you would consider helpful for SUMO contributors to know, based on your experience in the community forums?
That the browser is always changing & websites aren’t making sure they work in Firefox anymore. So it’s going to become more noticeable in the questions they see that certain websites are going to break more often & add-ons are going to break websites as well.
My advice would be to treat all antivirus software & all add-ons as the source of a weird issue the user is seeing. 95%+ of all problems dealing with websites not working or having a weird glitch are caused by add-ons, antivirus add-ons or the antivirus software itself intercepting all the internet traffic & blocking the wrong things causing the website to fail in Firefox.
Q: What excites you the most about Firefox development these days?
How there seems to be a refocused & dedicated effort to fix things that users are annoyed with & to build features they actually want.
Q: What are the biggest challenges you’re facing as a SUMO contributor at the moment? What would you like to see from us in the future?
SUMO is a great community and I think we just need a few more tools to reduce repetitive tasks. One idea is to be able to save personal canned responses for each forum helper so they don’t have to copy & paste them from their personal notes. Another could be to help us view a more cleanly formatted list of a user’s add-on in the System Details area. So we can take a look quickly without parsing a very large amount of JSON to find that information.
The biggest challenge I feel like is not knowing if a user had their problem resolved. Since the way people interact with forums has changed thanks to social media, they don’t really have the time to come back & post a reply. So sometimes they just give a thumbs up to our post. Which makes me wonder, does that mean my answer solved their problem? I think the thumbs up is the new way of saying your answer solved their issue. So maybe surfacing that information in a easy to see place will help me know my impact on resolving problems.
Jscher did something clever about that on his “My Questions” SUMO Contributor tool that shows a heart emoji/❤️at the top of your post if any user liked/your post.
Q: Can you tell us a story about the most rewarding moment and impactful contribution you’ve made in SUMO?
This is a tough but good question. It’s kinda hard to remember since I can’t search my answers past a certain point. But there have been a few big battles where I’ve totally forgot that I helped with. Thankfully Bugzilla has a lot of the big ones I helped solve.
One big moment was helping identify the cause of Firefox autoupdates failing for many users & they kept getting error popups about the failed updates. I could see this was going to get worse fast so I filed a bug and included as much of my findings as I could. And a Firefox dev (the awesome Nick Alexander) confirmed my findings & escalated the bug to NordVPN. It took a while (3 weeks) but NordVPN finally fixed it.
I think the most impactful contribution was giving feedback & filing bugs about site enhancements, moderation tools and site usability to SUMO over the years to make it easier & more productive for users, contributors and moderators to use the site. Special shout out to the team who originally built SUMO & helped build all our ideas into reality: Kadir Topal, Ricky Rosario, Mike Cooper, Will Kahn-Greene and Rehan Dalal. I really couldn’t have gotten anything done without this amazing team.
Q: You’ve had a few chances to meet with SUMO staff and other contributors in the past. Can you tell us more about the most productive in-person event or meeting you’ve had? What value did you get from these events?
These in-person events have been amazing. Maybe I can even say life changing because I was able to meet genuinely good people that I was able to call friends and some best friends. From what I’ve seen, Mozilla has the tendency to attract very smart people but also ones who help develop you into a better person through all the interactions you have with them.
Q: What advice would you give to someone new who wants to contribute to SUMO?
Take your time contributing. You don’t have to rush out a specific number of answers or KB article edits a day. You don’t even have to volunteer to help every day of the week. Work at your own pace. Either super slow, regular slow or just average speed. The Knowledge Base where all our support articles live will always be there. So you don’t have to rush to 100% completion to translate them to your locale. And on the forum side, the amount of questions that come to the SUMO platform are endless. Worse than that, not everyone you provide an answer to will respond back. So you may have wasted a lot of time customizing & curating a really good answer for someone, just to have them never respond at all or just put a simple thumbs down vote on your post. That’s happened to me quite a few times & I didn’t love it. So you could use my motto: Quality over quantity. A few quality posts here & there over posting 50 quick answers to which no one might reply.
That strategy/mantra will help you from burning out quickly.
And to counteract that missing feeling of engagement, I cherry pick forum questions that I think have a higher chance of reply based on how the person has stated their problem & if they seem invested in getting an answer. It’s tricky to do & you don’t always get it right. But developing this skill over time can help you respond to better people who will engage back with you & actually let you know if your advice helped or failed them. Which is where I get the most satisfaction from.

Not too much happened this week. Most regressions of note were readily justified as removing sources of unpredictable/inconsistent behavior from code-generation. There was one notable improvement, from PR #130561: avoiding redoing a redundant normalization of the param-env ended up improving compile times for 93 primary benchmarks by -1.0% on average.

New users feel like iteration times are so slow and it takes forever to get going with Rust. But if there's a library available, I feel like I'm roughly as productive with Rust as I am with Ruby, if not more, when I think about the whole amount of work I'm doing. I haven't really figured out how to talk about that without sounding purely like a zealot, but yeah, I feel like Rust is actually very, very productive, even though many people don't see it that way initially.
ESR115 EOL was extended for Win 7-8.1 and macOS 10.12-10.14 to March 2025. See the firefox-dev post for more details. This doesn’t impact next month’s planned migration to ESR128 for other OSes, however.
The topic selection experiment is running! Firefox users in the treatment branch will see a dialog asking if they want to choose specific topics to appear in their story recommendations:
There has been a lot of work on various parts of ScotchBonnet for the Address Bar. We will be looking to enable this in Nightly soon, so anyone wanting a sneak peek can toggle browser.urlbar.scotchBonnet.enableOverride to true. Bug reports and feedback are welcome!
mconley fixed a bug with the experimental automatic Picture-in-Picture feature that caused a perma-spinner to appear when tearing a tab out.
:eeejay has landed ARIA Element reflection that allows ARIA relationship attributes to be set in JavaScript by directly referencing target elements. In particular, it will allow setting ARIA relationship attributes to work across Shadow DOM boundaries (with limitations). It is now available behind the pref accessibility.ARIAElementReflection.enabled and is getting ready to be shipped (bug).

The ESLint rule no-shadow is now turned on by default. It is set to warning for system modules where it currently fails, and off for other code areas where it fails. The failing code areas are listed in the .eslintrc-rollouts.js file and we’ll work on rolling it out over time.
Migration Improvements (read-only)
fchasen launched the experiment to encourage Firefox users without a Mozilla account to create one and sync, in order to have a safeguard against sudden hardware failure. We’re already seeing an uptick in accounts being created, and we’re eager for the experiment to conclude to determine which messaging variant had the most impact!
For backup, mconley landedsomepatches to disable backing up various history-related data stores if Firefox is configured to clear history on shutdown. There are also a series of patches in review to regenerate backups when users intentionally delete certain data.
mconley is working with the OMC team to develop a new simple messaging surface inside of the AppMenu panel to try some different variants of the “signed out” state for the accounts item at the top of the menu

The Thunderbird Council is an important part of the Thunderbird story, and one of the main reasons we’re still around. In this month’s office hours, we sat down to chat with one of the very first Thunderbird Council members, Patrick Cloke, and one of the newest, Danny Colin, to discuss what this key group does and offers advice for those thinking about running in future elections.
Next month, we’ll put out a call for questions on socialmedia and on the relevant TopicBox mailing lists for our next Office Hours, which will feature Ryan Sipes, Managing Director of Product at MZLA and Mark Surman, executive director of the Mozilla Foundation!
September Office Hours: The Thunderbird Council
While Thunderbird has been around almost 20 years, the Council hasn’t always been a part of it. In 2012, Mozilla discontinued support for Thunderbird as a product, but our community stepped in. In 2014, core contributors met in Toronto and elected the first Thunderbird Council to guide the project. For many years, the council was responsible for the day-to-day responsibilities, including development, budgeting, and hiring. While MZLA now handles those operations, the council has an even more crucial role. In the video, Danny and Patrick explain how the modern-day council works with MZLA and serves as the community’s voice.
Want to know more about what council members do, or who can run for council? Our guests provide honest and encouraging answers to these questions. Basically, if you’re an active contributor who cares about Thunderbird, you might consider running!
Watch, Read, and Get Involved
We’re so grateful to Danny and Patrick for joining us! We hope this video helps explain more about the Thunderbird Council’s role, and even encourages some of you who are active Thunderbird contributors to consider running in the future. And if you’re not an active contributor yet, go to our website to learn how to get involved!
The Rust compiler has recently upgraded to using LLVM 19 and this
change accompanies some updates to the default set of target features enabled
for WebAssembly targets of the Rust compiler. Beta Rust today, which will
become Rust 1.82 on 2024-10-17, reflects all of these changes and can be
used for testing.
WebAssembly is an evolving standard where extensions are being added over
time through a proposals process. WebAssembly proposals reach
maturity, get merged into the specification itself, get implemented in engines,
and remain this way for quite some time before producer toolchains (e.g. LLVM)
update to enable these sufficiently-mature proposals by default. In LLVM 19
this has happened with the multi-value and reference-types
proposals for the LLVM/Rust target features multivalue and
reference-types. These are now enabled by default in LLVM and transitively
means that it's enabled by default for Rust as well.
WebAssembly targets for Rust now have improved
documentation about WebAssembly
proposals and their corresponding target features. This post is going to review
these changes and go into depth about what's changing in LLVM.
WebAssembly Proposals and Compiler Target Features
WebAssembly proposals are the formal means by which the WebAssembly standard
itself is evolved over time. Most proposals need toolchain integration in one
form or another, for example new flags in LLVM or the Rust compiler. The
-Ctarget-feature=... mechanism is used to implement this today. This is a
signal to LLVM and the Rust compiler which WebAssembly proposals are enabled or
disabled.
There is a loose coupling between the name of a proposal (often the name of the
github repository of the proposal) and the feature name LLVM/Rust use. For
example there is the multi-value
proposal but a multivalue
feature.
The lifecycle of the implementation of a feature in Rust/LLVM typically looks
like:
A new WebAssembly proposal is created in a new repository, for example
WebAssembly/foo.
Eventually Rust/LLVM implement the proposal under -Ctarget-feature=+foo
Eventually the upstream proposal is merged into the specification, and
WebAssembly/foo becomes an archived repository
Rust/LLVM enable the -Ctarget-feature=+foo feature by default but typically
retain the ability to disable it as well.
The reference-types and multivalue target features in Rust are at step (4)
here now and this post is explaining the consequences of doing so.
Enabling Reference Types by Default
The reference-types proposal to
WebAssembly introduced a few
new concepts to WebAssembly, notably the externref type which is a
host-defined GC resource that WebAssembly cannot access but can pass around.
Rust does not have support for the WebAssembly externref type and LLVM 19 does
not change that. WebAssembly modules produced from Rust will continue to not use
the externref type nor have a means of being able to do so. This may be
enabled in the future (e.g. a hypothetical core::arch::wasm32::Externref type
or similar), but it will mostly likely only be done on an opt-in basis
and will not affect preexisting code by default.
Also included in the reference-types proposal, however, was the ability to have
multiple WebAssembly tables in a single module. In the original version of the
WebAssembly specification only a single table was allowed and this restriction
was relaxed with the reference-types proposal. WebAssembly tables are used by
LLVM and Rust to implement indirect function calls. For example function
pointers in WebAssembly are actually table indices and indirect function calls
are a WebAssembly call_indirect instruction with this table index.
With the reference-types proposal the binary encoding of call_indirect
instructions was updated. Prior to the reference-types proposal call_indirect
was encoded with a fixed zero byte in its instruction (required to be exactly
0x00). This fixed zero byte was relaxed to a 32-bit LEB to indicate which
table the call_indirect instruction was using. For those unfamiliar LEB is a
way of encoding multi-byte integers in a smaller number of bytes for smaller
integers. For example the 32-bit integer 0 can be encoded as 0x00 with a
LEB. LEBs are flexible to additionally allow "overlong" encodings so the
integer 0 can additionally be encoded as 0x80 0x00.
LLVM's support of separate compilation of source code to a WebAssembly binary
means that when an object file is emitted it does not know the final index of
the table that is going to be used in the final binary. Before reference-types
there was only one option, table 0, so 0x00 was always used when encoding
call_indirect instructions. After reference-types, however, LLVM will emit an
over-long LEB of the form 0x80 0x80 0x80 0x80 0x00 which is the maximal
length of a 32-bit LEB. This LEB is then filled in by the linker with a
relocation to the actual table index that is used by the final module.
When putting all of this together, it means that with LLVM 19, which has
the reference-types feature enabled by default, any WebAssembly module with an
indirect function call (which is almost always the case for Rust code) will
produce a WebAssembly binary that cannot be decoded by engines and tooling that
do not support the reference-types proposal. It is expected that this change
will have a low impact due to the age of the reference-types proposal and
breadth of implementation in engines. Given the multitude of WebAssembly
engines, however, it's recommended that any WebAssembly users test out
Rust 1.82 beta and see if the produced module still runs on their engine of
choice.
LLVM, Rust, and Multiple Tables
One interesting point worth mentioning is that despite the reference-types
proposal enabling multiple tables in WebAssembly modules this is not actually
taken advantage of at this time by either LLVM or Rust. WebAssembly modules
emitted will still have at most one table of functions. This means that the
over-long 5-byte encoding of index 0 as 0x80 0x80 0x80 0x80 0x00 is not
actually necessary at this time. LLD, LLVM's linker for WebAssembly, wants to
process all LEB relocations in a similar manner which currently forces this
5-byte encoding of zero. For example when a function calls another function the
call instruction encodes the target function index as a 5-byte LEB which is
filled in by the linker. There is quite often more than one function so the
5-byte encoding enables all possible function indices to be encoded.
In the future LLVM might start using multiple tables as well. For example LLVM
may have a mode in the future where there's a table-per-function type instead of
a single heterogenous table. This can enable engines to implement
call_indirect more efficiently. This is not implemented at this time, however.
For users who want a minimally-sized WebAssembly module (e.g. if you're in a web
context and sending bytes over the wire) it's recommended to use an optimization
tool such as wasm-opt to shrink the size of the output of LLVM. Even before
this change with reference-types it's recommended to do this as wasm-opt can
typically optimize LLVM's default output even further. When optimizing a module
through wasm-opt these 5-byte encodings of index 0 are all shrunk to a
single byte.
Enabling Multi-Value by Default
The second feature enabled by default in LLVM 19 is multivalue. The
multi-value proposal to WebAssembly enables functions to have
more than one return value for example. WebAssembly instructions are
additionally allowed to have more than one return value as well. This proposal
is one of the first to get merged into the WebAssembly specification after the
original MVP and has been implemented in many engines for quite some time.
The consequences of enabling this feature by default in LLVM are more minor for
Rust, however, than enabling the reference-types feature by default. LLVM's
default C ABI for WebAssembly code is not changing even when multivalue is
enabled. Additionally Rust's extern "C" ABI for WebAssembly is not changing
either and continues to match LLVM's (or strives to, differences to
LLVM are considered bugs to
fix). Despite this though the change has the possibility of still affecting
Rust users.
Rust for some time has supported an extern "wasm" ABI on Nightly which was an
experimental means of exposing the ability of defining a function in Rust which
returned multiple values (e.g. used the multi-value proposal). Due to
infrastructural changes and refactorings in LLVM itself this feature of Rust has
been removed and is no longer
supported on Nightly at all. As a result there is no longer any possible method
of writing a function in Rust that returns multiple values at the WebAssembly
function type level.
In summary this change is expected to not affect any Rust code in the wild
unless you were using the Nightly feature of extern "wasm" in which case
you'll be forced to drop support for that and use extern "C" instead.
Supporting WebAssembly multi-return functions in Rust is a broader topic than
this post can cover, but at this time it's an area that's ripe for contribution
from suitably motivated contributors.
Aside: ABI Stability and WebAssembly
While on the topic of ABIs and the multivalue feature it's perhaps worth
also going over a bit what ABIs mean for WebAssembly. The current definition of
the extern "C" ABI for WebAssembly is documented in the tool-conventions
repository
and this is what Clang implements for C code as well. LLVM implements enough
support for lowering to WebAssembly as well to support all of this. The extern "Rust ABI is not stable on WebAssembly, as is the case for all Rust targets,
and is subject to change over time. There is no reference documentation at this
time for what extern "Rust" is on WebAssembly.
The extern "C" ABI, what C code uses by default as well, is difficult to
change because stability is often required across different compiler versions.
For example WebAssembly code compiled with LLVM 18 might be expected to work
with code compiled by LLVM 20. This means that changing the ABI is a daunting
task that requires version fields, explicit markers, etc, to help prevent
mismatches.
The extern "Rust" ABI, however, is subject to change over time. A great
example of this could be that when the multivalue feature is enabled the
extern "Rust" ABI could be redefined to use the multiple-return-values that
WebAssembly would then support. This would enable much more efficient returns
of values larger than 64-bits. Implementing this would require support in LLVM
though which is not currently present.
This all means that actually using multiple-returns in functions, or the
WebAssembly feature that the multivalue enables, is still out on the horizon
and not implemented. First LLVM will need to implement complete lowering support
to generate WebAssembly functions with multiple returns, and then extern "Rust" can be change to use this when fully supported. In the yet-further-still
future C code might be able to change, but that will take quite some time due to
its cross-version-compatibility story.
Enabling Future Proposals to WebAssembly
This is not the first time that a WebAssembly proposal has gone from
off-by-default to on-by-default in LLVM, nor will it be the last. For example
LLVM already enables the sign-extension proposal by default which
MVP WebAssembly did not have. It's expected that in the not-too-distant future
the
nontrapping-fp-to-int
proposal will likely be enabled by default. These changes are currently not made
with strict criteria in mind (e.g. N engines must have this implemented for M
years), and there may be breakage that happens.
If you're using a WebAssembly engine that does not support the modules emitted
by Rust 1.82 beta and LLVM 19 then your options are:
Try seeing if the engine you're using has any updates available to it. You
might be using an older version which didn't support a feature but a newer
version supports the feature.
Open an issue to raise awareness that a change is causing breakage. This could
either be done on your engine's repository, the Rust repository, or the
WebAssembly
tool-conventions
repository. It's recommended to first search to confirm there isn't already an
open issue though.
Recompile your code with features disabled, more on this in the next section.
The general assumption behind enabling new features by default is that it's a
relatively hassle-free operation for end users while bringing performance
benefits for everyone (e.g. nontrapping-fp-to-int will make float-to-int
conversions more optimal). If updates end up causing hassle it's best to flag
that early on so rollout plans can be adjusted if needed.
Disabling on-by-default WebAssembly proposals
For a variety of reasons you might be motivated to disable on-by-default
WebAssembly features: for example maybe your engine is difficult to update or
doesn't support a new feature. Disabling on-by-default features is unfortunately
not the easiest task. It is notably not sufficient to use
-Ctarget-features=-sign-ext to disable a feature for just your own project's
compilation because the Rust standard library, shipped in precompiled form, is
still compiled with the feature enabled.
To disable on-by-default WebAssembly proposal it's required that you use Cargo's
-Zbuild-std
feature. For example:
This will recompiled the Rust standard library in addition to your own code with
the "MVP CPU" which is LLVM's placeholder for all WebAssembly proposals
disabled. This will disable sign-ext, reference-types, multi-value, etc.
Developer Tools help developers write and debug websites on Firefox. This newsletter gives an overview of the work we’ve done as part of the Firefox 130 Nightly release cycle.
Firefox being an open source project, we are grateful to get contributions from people outside of Mozilla, like Artem Manushenkov who made the Inspector show the dimension of the page in an overlay when the window is resized (#1826409)
We got a report for what we call zombie breakpoints, aka breakpoints that are still seen as active by the engine, even if the user removed it from the client. This was affecting WebExtension debugging and should be fixed now (#1908095).
Speaking of the Debugger, pretty printing got almost 30% faster and opening large files 10% faster (#1907794). This is due to some work on some work on Cycle Collection in Javascript Workers, which the Debugger is using when opening a Javascript profile to parse its content. We’re currently doing more work to optimize opening files even faster, so stay tunes for even better numbers soon!
Finally, we fixed local script override for Service Worker cached requests (#1876060) and scripts with crossorigin attributes (#1834799).
… and quality of life Inspector improvements
In the markup view, you can now add attributes in the input that appears when you double click the tagname (#1173057).
You might now know it, but by default, the Inspector element picker ignores nodes with pointer-events: none , as those are often used as absolutely positioned on the whole page and would prevent to pick items underneath it. In the cases where you do want to pick those non-targetable element, you can hold Shift while using the element picker. In 130, we ensured that pressing Shift will change the behavior directly instead of waiting for the next mouse move (#1899704).
That’s it for this months, this post is shorter than usual as most of the team is working on longer projects that are not shipping yet, but hopefully we can talk about them in the coming months! Thank you for reading this and using our tools, see you in a few weeks for a new round of updates
Full list of fixed bugs in DevTools for the Firefox 130 release:
Boris Chiou [:boris] InspectorUtils.getCSSStyleRules only returns nested CSSStartingStyleRule rules of rules with selectors using children/descendent combinator in their selectors (#1905035)
:gerard-majax devtools test might run into race on process kill with forkserver (#1906816)
Masayuki Nakano `TextPropertyEditor.prototype._draggingOnMouseDown` uses `Element.setPointerCapture` with `undefined` (#1907489)
Masayuki Nakano `Draggable.startDragging` uses `Element.setPointerCapture` with `undefined` (#1907490)
Masayuki Nakano `LinearEasingFunctionWidget.#onMouseDown` uses `Element.setPointerCapture` with `undefined` (#1907494)
Olli Pettay Very long cycle collection times (4.3s) in parser-worker.js (#1907794)
Julian Descottes [:jdescottes] Intermittent devtools/client/inspector/rules/test/browser_rules_add-rule-then-property-edit-selector.js | single tracking bug (#1899341)
Nicolas Chevobbe [:nchevobbe] When inspecting some “pointer-events: none” elements in a page, pressing shift should change the behavior without waiting for mousemove (#1899704)
The Rust 2024 edition is on track to be stabilized on Nightly by Nov 28 and to reach stable as part of Rust v1.85, to be released Feb 20, 2025.
Over the last month, all the "lang team priority items" have landed and are fully ready for release, including migrations and chapters in the Nightly version of the edition guide:
Keep in mind, there will be items that are currently tracked for the edition that will not make it. That's OK, and we still plan to ship the edition on time and without those items.
We are generally on track with our marquee features:
Support for async closures is available on Nightly and the lang team arrived at a tentative consensus to keep the existing syntax (written rationale and formal decision are in progress). We issued a call for testing as well which has so far uncovered no issues.
Partial support for return-type notation is available on Nightly with the remainder under review.
In addition, dynamic dispatch for async functions and experimental async drop work both made implementation progress. Async WG reorganization has made no progress.
RFL on Rust CI is implemented but still waiting on documented policy. The first breakage was detected (and fixed) in #129416. This is the mechanism working as intended, although it would also be useful to better define what to do when breakage occurs.
Selected updates
Begin resolving cargo-semver-checks blockers for merging into cargo (tracked in #104)
@obi1kenobi has been working on laying the groundwork to enable manifest linting in their project. They have set up the ability to test how CLI invocations are interpreted internally, and can now snapshot the output of any CLI invocation over a given workspace. They have also designed the expansion of the CLI and the necessary Trustfall schema changes to support manifest linting. As of the latest update, they have a working prototype of manifest querying, which enables SemVer lints such as detecting the accidental removal of features between releases. This work is not blocked on anything, and while there are no immediate opportunities to contribute, they indicate there will be some in future updates.
Expose experimental LLVM features for automatic differentiation and GPU offloading (tracked in #109)
@ZuseZ4 has been focusing on automatic differentiation in Rust, with their first two upstreaming PRs for the rustc frontend and backend merged, and a third PR covering changes to rustc_codegen_llvm currently under review. They are especially proud of getting a detailed LLVM-IR reproducer from a Rust developer for an Enzyme core issue, which will help with debugging. On the GPU side, @ZuseZ4 is taking advantage of recent LLVM updates to rustc that enable more GPU/offloading work. @ZuseZ4 also had a talk about "When unsafe code is slow - Automatic Differentiation in Rust" accepted for the upcoming LLVM dev meeting, where they'll present benchmarks and analysis comparing Rust-Enzyme to the C++ Enzyme frontend.
Extend pubgrub to match cargo's dependency resolution (tracked in #110)
@Eh2406 has achieved the milestone of having the new PubGrub resolver and the existing Cargo resolver accept each other's solutions for all crate versions on crates.io, which involved fixing many bugs related to optional dependencies. Significant progress has also been made in speeding up the resolution process, with over 30% improvements to the average performance of the new resolver, and important changes to allow the existing Cargo resolver to run in parallel. They have also addressed some corner cases where the existing resolver would not accept certain records, and added a check for cyclic dependencies. The latest updates focus on further performance improvements, with the new resolver now taking around 3 hours to process all of crates.io, down from 4.3 hours previously, and a 27% improvement in verifying lock files for non-pathological cases.
Optimizing Clippy & linting
@blyxyas has been working on improving Clippy, the Rust linting tool, with a focus on performance. They have completed a medium-sized objective to use ControlFlow in more places, and have integrated a performance-related issue into their project. A performance-focused PR has also been merged, and they are remaking their benchmarking tool (benchv2) to help with ongoing efforts. The main focus has been on resolving rust-lang/rust#125116, which is now all green after some work. Going forward, they are working on moving the declare_clippy_lint macro to a macro_rules implementation, and have one open proposal-level issue with the performance project label. There are currently no blockers to their work.
Several goals appear to have stalled or not received updates:
Associated type position impl trait made significant progress but was not able to reach a stabilizable state before its owner had to scale back their activity. We expect to revisit this in 2025H1.
This is a brief summary of the progress towards our a subset of the 2024 project goals. There is a lot more information available on the website, including the motivation for each goal, as well as detailed status updates. If you'd like more detail, please do check it out! You can also subscribe to individual tracking issues (or the entire rust-project-goals repo) to get regular updates.
The current set of goals target the second half of 2024 (2024H2). Next month we also expect to begin soliciting goals for the first half of 2025 (2025H1).
(Previously: PET projects or real privacy?) The current trend for privacy-enhancing technologies for surveillance in web browsers are going to be remembered as a technical dead end, an artifact of an unsustainable advertising oligopoly. Here’s a top ten list of reasons, will update and add links.
10. PETs don’t fix revenue issues for ad-supported sites. The fundamental good ad/bad site problems and bad ad/good site problems are still there. PETs make it safer and easier for an advertiser to run ads on sites they don’t trust, so they help crappy infringing or AI-generated sites compete with legit ones in the same ways that third-party cookies do.
9. PETs give up the high ground and make the web just another incomprehensible, creepy surveillance medium. When people complain about privacy issues on native social media apps, with PETs the app people can just say, your browser is creepy now too, we’re just better at business than web sites are.
8. Appeasement doesn’t work. In all the time that PET proponents have been saying that surveillance marketers will mend their ways if they have PETs as a compromise, how many data points have the surveillance marketers chosen not to collect because they have PETs instead? (The way to deal with boundary-testing is not to appease it, it’s to communicate the boundary, communicate the conseqences for crossing it, and make the consequences happen. I had a good source for this, need to find it again.)
7. Only a few platform oligopolies and monopolies benefit from PETs. PETs introduce noise and obfuscation, to make data interpretation only practical above a certain data set size—for a few large companies (or one?) On this point, they’re worse than third-party cookies.
5. If it’s a good idea for shoppers to share their info, obfuscated, with advertisers, why not make the browser share the info from corporate web apps with customers, with individual employee identifying details removed? What? Companies wouldn’t turn that feature on? Then why would users?
4. The code complexity and client-side resource usage—along with the inevitable security risks that come with running more code—end up being paid by users, while the benefits go to surveillance companies. And the additional server-side processing required to do all that privacy-enhancing math on all those zillions of cleverly scrambled data points means that Big Tech companies will build even more big data centers, consume more energy and fresh water, and delay those carbon-neutral goals yet again.
3. With PETs, information becomes available equally to both trusted and untrusted parties. In a sustainable advertising medium, a trusted publisher or channel has more audience information than an untrustworthy one. PETs commoditize ad inventory, create more incentives for surveillance of users using non-PET methods, and promote a race to the bottom the same way that cookies do.
2. For most people, individual tracking isn’t the problem. Users are concerned about group-level discrimination risks like surveillance pricing and algorithmic discrimination, and PETs would only obfuscate the risks, not reduce them, and make discrimination harder for regulators and NGOs to detect.
1. Never mind, you didn’t have to read this list. Browser companies already know that PETs are creepy and bad, and you can tell they know because they hide PETs from users, either with a bullshit Got it dialog, or buried under Advanced or something. If PETs were good for users, the browsers would brag on them like they do other features.
<figcaption>The HTML and CSS inspector is able to display the DOM elements and their attributes and CSS properties.</figcaption>
Servo has been working on improving our Firefox devtools support as part of the Outreachy internship program since June, and we’re thrilled to share significant progress.
Devtools are a set of browser web developer tools that allows you to examine, edit, and debug HTML, CSS, and JavaScript.
Servo leverages existing work from the Firefox devtools to inspect its own websites, employing the same open protocol that is used for connecting to other Firefox instances.
While relying on a third party API allows us to offer this functionality without building it from scratch, it doesn’t come without downsides.
Back in June last year, with the release of Firefox 110, changes to the protocol broke our previous implementation.
The core issue was that the message structure sent between Servo and Firefox for the devtools functionality had changed.
To address this, we first updated an existing patch to fix the connection and list the webviews running in Servo (@fabricedesre, @eerii, @mrobinson, #32475).
We also had to update the structure of some actors (pieces of code that respond to messages sent by Firefox with relevant information), since they changed significantly (@eerii, #32509).
One of the main challenges was figuring out the messages we needed to send back to Firefox.
The source code for their devtools implementation is very well commented and proved to be invaluable.
However, it was also helpful to see the actual messages being sent.
While Servo can show the ones it sends and receives, debugging another instance of Firefox to observe its messages was very useful.
To facilitate this, we made a helper script (@eerii, #32684) using Wireshark to inspect the connection between the devtools client and server, allowing us to view the contents of each packet and search through them.
Support for the console was fixed, enabling the execution of JavaScript code directly in Servo’s webviews and displaying any warnings or errors that the page emits (@eerii, @mrobinson, #32727).
<figcaption>The JavaScript developer console now displays page logs.
It can also run commands.</figcaption>
Finally, the most significant changes involved the DOM inspector.
Tighter integration with Servo’s script module was required to retrieve the properties of each element.
Viewing CSS styles was particularly challenging, since they can come from many places, including the style attribute, a stylesheet, or from ancestors, but @emilio had great insight into where to look.
As a result, it’s now possible to view the HTML tree, and add, remove, or modify any attribute or CSS property (@eerii, @mrobinson, #32655, #32884, #32888, #33025).
There is still work to be done.
Some valuable features like the Network and Storage tabs are still not functional, and parts of the DOM inspector are still barebones.
For example, now that flexbox is enabled by default (@mrobinson, #33186), it would be a good idea to support it in the Layout panel.
We’re working on developer documentation that will be available in the Servo book to make future contributions easier.
That said, the Console and Inspector support has largely landed, and you can enable them with the --devtools flag in servoshell.
For a step-by-step guide on how to use Servo’s devtools, check out the new devtools chapter in the Servo book.
We’d love to hear your feedback on how these work and what additional features you’d find helpful in your workflow.
Many thanks to @eerii and Outreachy for the internship that made this possible!
Firefox Recommended Extensions comprise a collection of featured content that’s been curated with extensive community involvement. It’s time once again to form a new Recommended Extensions Community Advisory Board and launch a fresh curatorial project. The project goal is to identify a new batch of exceptional extensions that should be considered for the Recommended program (Firefox desktop and Android).
Participation on the Community Advisory Board is a great opportunity to make a major impact with millions of users. More than 25% of all Firefox extension installs are from the Recommended set.
Past board members have included developers, designers, or simply power users. Technical skills are not required, but a passion and appreciation for great extensions are.
The evaluation process focuses on extension functionality (does it perform exceptionally well?), user experience (is it elegant and intuitive to operate?), or otherwise distinct characteristics (does it offer a unique feature or reimagine a familiar utility in a fresh way?). The project will last six months and participation is as simple as trying out a few extensions per month and offering feedback.
October 18 application deadline!
If you’re interested in contributing your perspective to the Recommended Extensions curatorial process, please complete this form by October 18th. Thank you!
Thunderbird and its features help you do things. Crossing things off your to-do list means getting your time and energy back. Using Thunderbird and its Add-ons for productivity? Now that’s how you take your workflow to the next level.
One of Thunderbird’s biggest strengths is its vibrant, community-driven Add-ons. Many of those Add-ons are all about helping you get more out of Thunderbird. We asked our community what Add-ons they were using and would recommend to readers in this post. And did our community respond! You can read all of the recommendations from our community on Mastodon, Reddit, X (formerly Twitter) and LinkedIn.
We’re grateful for all the recommendations and for all of our Add-on developers! They put their personal time into making Thunderbird even more incredible through their extensions. The Add-ons in this list are only a small, small subset of all the active ones. We highly encourage you to check out the whole wide world of Add-ons out there.
(And if you’re wondering, I’ve downloaded Quicktext and Markdown Here Revival for my own workflow.)
Add-Ons to Try Today: Folders and Accounts
Border Colors D – Having all your email accounts in one app is already a productivity boost. What’s not productive is accidentally sending a message from the wrong account. Border Colors D allows you to assign a color and other visual indicators to the New Message window for each account. If you’re a “power user with many accounts [who] can’t afford an oops when you send with the wrong source address,” this is the Add-on for you.
Quick Folder Move – Sorting messages into folders is a great way to keep the information in your email organized. (We love using folders to sort our inbox down to zero!) This Add-on brings up a search bar or your recent folders, and allows you to move messages with ease – especially if you have a lot of folders
Add-ons to Try Today: Inbox Views and Message Composition
Thunderbird Conversations – When “you need to see quickly all received and sent mails…very important in a context of a shared mail box,” a conversation view is great. While that view is something we’d love to see built in to Thunderbird, there’s work on our underlying database we need to do first. But this Add-on brings that view to Thunderbird, and to your inbox, now.
Markdown Here Revival – Is Markdown part of your productivity and workflow toolbox? This Add-on will allow you to write emails in Markdown and send them as HTML with the click of a button! One of our recommenders said this Add-on is “absolutely mandatory.”
Send Later – Sometimes, part of your productivity routine involves scheduling things to be sent later. Or, as the recommendation added, you don’t want your boss to know you were working on something at 2 am. This add-on adds true send later functionality to Thunderbird, so you decide when that message gets sent, whether it’s one time or regularly. (But really, night owls, sleep is good!)
Add-Ons to Test Today!
A few of our community’s favorite Add-ons are in beta testing for their fully 128-compatible versions, as of September 2024. Testing is one of the best and most beginner-friendly ways to contribute to Thunderbird. If you’d like to boost your productivity AND make a developer’s day, we have two Add-ons we’d encourage you to check out.
Our community loves Nostalgy++, especially on Reddit. Nostalgy++ brings the power of keyboard shortcuts to Thunderbird to let you manage, search, and archive emails. One user says they save hours every week thanks to Nostalgy++’s keybindings. Nostalgy++ is still beta testing for its 128-compatible release. Testing is one of the most useful and newcomer-friendly ways to contribute to Thunderbird, and we encourage you to check out their latest release and report your experience on the Add-on’s GitHub page.
Remove Duplicate Message is another Add-on that is also seeking beta testers for their 128-compatible version. For anyone who has ever dealt with replies to a “catch-all” email address or anything else cluttering their inbox with duplicates, this Add-on can take care of those copies for you. Check out their latest release and provide feedback on their GitHub Issues.

In July 2024, the U.S. AI Safety Institute (AISI), under the National Institute of Standards and Technology (NIST) released draft guidance on Managing Misuse Risk for Dual-Use Foundation Models. This draft, intended for public comment, is focused specifically on foundation models – the largest and most advanced AI models available – and namely those built by closed model developers in big tech labs. The AI Safety Institute’s framework laid out in the document “focuses on managing the risk that models will be deliberately misused to cause harm…”
According to NIST’s AISI, the document is meant to build on the existing AI Risk Management Framework (to which Mozilla provided comments) to address both the technical and social aspects of misuse risks by providing best practices for organizations.
Mozilla takes seriously its role as a steward of good practices, especially when it comes to protecting open-source, privacy, and fighting for the principles in Mozilla’s Manifesto. We’ve led the way in advancing safer and more trustworthy AI, releasing an in-depth report on Creating Trustworthy AI in 2020 and bringing together forty AI leaders to discuss critical questions related to openness and AI at the 2024 Columbia Convening. As such, Mozilla encourages legislators and regulators to do their part and protect the interests of individuals and to make technology more useful and accessible for all.
However, while the AISI draft guidelines do an excellent job in highlighting the theoretical risks posed by foundation models created by large and largely private developers, it takes a narrow view of the way AI is developed today, including at the current technology frontier. In our full comments, we focused on encouraging the AISI to expand the lens through which it examines how AI is developed today. In particular, we believe that the AISI should work to ensure that its guidelines are adapted to take into account the unique nature of open source. Below is a list of highlights from Mozilla’s comments on the existing draft:
The current draft focuses on AI services deployed on the internet and accessed through some interface or API. The reality is that the majority of AI research and development is occurring on locally deployed AI models that are collaboratively developed and freely distributed. NIST should rework the draft’s front matter and glossary to better capture the state of the AI ecosystem.
The practices outlined in the draft place a disproportionate burden on any AI developer outside of the small handful of very large AI companies. Mozilla believes that NIST should ensure that requirements are applicable to organizations of all sizes and capability levels, and should take into account the potential negative impact of misuse at different organizational scales.
The recommendations for implementing the practices outlined in the draft imply that the AI model is centrally controlled and deployed. Open-source and collaborative development environments don’t align with this approach, rendering this guidance inapplicable, unhelpful, or at worst – harmful. Given the strong evidentiary basis for open-source helping mitigate risk and make software safer, NIST should ensure open-source AI is considered and supported in its work.
The document should define “gradients of access” as a way to provide a framework for AI risk management discussions and decision making. These gradients should represent incremental steps of access to an AI model (e.g. chat interface, prompt injection, training, direct weights visibility, local download, etc.) and each should be accompanied by its associated risks.
We hope that the AI Safety Institute continues to build on its foundational work in the field and works to develop guidelines, recommendations, and best practices that will not only stand the test of time but take into account the broader field of participants in the AI ecosystem. When such regulations are well designed, they propel the AI sector towards a safer and more trustworthy future.

Dealing with spam in our daily email routines can be frustrating, but Thunderbird has some tools to make unwanted messages less of a headache. It takes time, training, and patience, but eventually you can emerge victorious over that junk mail. In this article we’ll explain how Thunderbird’s spam filter works, and how to tune it for the most effective results.
What Powers Thunderbird’s Spam Filter?
Thunderbird’s adaptive filter uses one of the oldest methods around — a Bayes algorithm — to help decide which messages should be marked as junk. But in order to work efficiently and reliably, it also needs a little help from you.
Thunderbird’s documentation and support community have always mentioned that the spam filter needs some human intervention, but I never understood why until researching how a Bayes algorithm works.
Why A Bayes Algorithm Needs Your Help
It’s helpful to think about Thunderbird’s spam filter as a sort of inbox detective, but you’re instrumental in training it and making it smarter. That’s because a Bayes algorithm calculates the odds that an email is spam based on the words it contains, and uses past experience to make an educated guess.
Here’s an example: you receive an email that contains the words “Urgent, act now to claim your free prize!” The algorithm checks to see how frequently those words appear in known spam messages compared to known good messages. If it detects those words (especially ones like “free” and “prize,”) are frequently in messages you’ve marked as spam, but not present in good messages, it will mark it as junk.
This is why it’s equally important to mark messages as “Not Junk.” Then, it learns to recognize “good” words that are common across non-spam emails. And for each message you mark, the probability that Thunderbird’s spam filter accurately identifies spam only increases.
Of course, it’s not perfect. A message you mark as junk might not consistently be marked as junk. A reliable, fail-safe way to ensure certain messages are marked as junk is to create filters manually.
Do you want to ensure important messages are never marked as junk? Try whitelisting.
Since junk mail patterns are always changing, it’s a good idea to regularly train Thunderbird. Without frequent training, it may not provide great results.
Junk Filter Settings
Now that we understand what powers Thunderbird’s junk filter, let’s look at how to manage the settings, and how to train Thunderbird for more consistent results.
Global Junk Settings
Junk filtering is enabled by default, but you can fine-tune what should happen to messages marked as junk using the global settings. These settings apply to all email accounts, though some can be overridden in the Per Account Settings.
Click the menu button (≡) > Settings > Privacy & Security.
Scroll down to Junk and adjust the settings to your preference.
Per Account Settings
The junk settings for each of your email accounts will override similar settings in the Global Settings.
Click the menu button (≡) > Account Settings > Your email address > Junk Settings.
How to Turn Off Thunderbird’s Adaptive Filtering
To disable Thunderbird’s adaptive junk mail controls:
Uncheck Enable adaptive junk mail controls for this account.
Whitelisting
Under Do not automatically mark mail as junk if the sender is in, you can select address books to use as a whitelist. Senders whose email addresses are in a whitelisted address book won’t be automatically marked as junk. However, you can still manually mark a message from a whitelisted sender as junk.
Enabling whitelisting is recommended to help ensure messages from people you care about are not marked as junk.
Training the Junk Filter
This part is important: for Thunderbird’s junk filter to be effective, you must train it to recognize both junk and non-junk messages. If you only do one or the other, the filter won’t be very effective.
It’s important to mark messages as junk before deleting them. Just deleting a message doesn’t train the filter.
Press J on your keyboard to mark one or more selected messages as junk.
Once you mark a message as junk, if you’ve configured your Global Junk Settings or Per Account Settings to move junk email to a different folder, the email will disappear from the Message List Pane. Don’t worry, the email has moved to the folder you’ve configured for junk mail.
Thunderbird’s junk filter is designed to learn from the training data you provide. Marking more messages as Junk or Not Junk will improve the accuracy of your junk filter by adding more training data.
Tell Thunderbird What is NOT Junk
Sometimes Thunderbird’s junk filter might mark good messages as junk. It’s important to tell the filter which messages are not junk, especially on a new installation of Thunderbird.
Note: Frequently (daily or weekly) check your Junk folder for good messages wrongly marked as junk and mark them as Not Junk. This will recover the good messages and improve the filter’s accuracy.
There are several ways to mark messages as Not Junk:
Click the Not Junk button in the yellow junk notification below the message header in the Message List Pane:
Click the red junk icon in the Junk column of the Message List Pane to toggle the junk status of a message:
Press Shift+J on your keyboard to mark one or more messages as Not Junk.
Once you unmark a message as junk, it will disappear from the current folder but will return to its original folder.
Repeated Training
Regularly train the filter by marking several good messages as not junk. This includes messages in your inbox and those filtered into other folders. Use the keyboard shortcut Shift+J for this, as the Not Junk button only appears for messages already marked as junk. Marking several messages per week will be sufficient, and you can select many messages to mark all at once.
Unfortunately, the user interface doesn’t indicate whether a message has already been marked as “not junk.”
Other Ways to Block Unwanted Messages
Thunderbird’s adaptive junk filter is not an absolute barrier against messages from specific addresses or types of messages. You can use stronger mechanisms to block unwanted messages:
Marco fixed a regression bug where the Mobile Bookmarks folder was no longer visible in the bookmarks menus – Bug 1913976
Amy, Maxx, Scott and Nathan have been working on some new layout variants for New Tab that we aim to experiment with in the next few releases. (Meta bug)
Try it in Nightly: (Set either of these prefs to True)
As part of follow ups to the Manifest V3 improvements, the extensions button setWhenClicked/setAlwaysOn context menu items have been fixed to account for the extension host permissions listed in the manifest and the ones already granted – Bug 1905146
We fixed a regression with the unlimitedStorage permission being revoked for extensions when users cleared recent history – Bug 1907732
Thanks to Gregory Pappas, the internals used by the tabs’s captureTab/captureVisibleTab API methods have been migrated to use OffscreenCanvas (and migrated away from using an hidden window) – Bug 1914102
WebExtension APIs
Fixed openedTabId for notified through tabs.onUpdated API event when changes through tabs.update API method – Bug 1409262
Fixed downloads.download API method throwing on folder names that contains a dot and a space – Bug 1903780
NOTE: this fix has been landed in Nightly 131, but it has been also uplifted to Firefox 130 and Firefox ESRs 128 and 115.
Fixed webRequest issues related to ChannelWrapper cached attributes missing to be invalidated on HTTP redirects (Bug 1909081, Bug 1909270)
Introduced quota enforcement to storage.session API – Bug 1908925
Emilio fixed an issue that was preventing users to modify CSS declarations in the Inspector for stylesheet imported into a layer (#1912996)
Nicolas tweaked the styling of focused element and inputs in the markup view so it’s less confusing (#1907803)
Nicolas made a few changes to improve custom properties in the Inspector
We’re now displaying the computed value of custom properties in the tooltip when it differs from the declaration value (#1626234), and made the different values displayed in the tooltip more colorful (#1912006)
And since we now have the computed values, it’s easy to show color swatches for CSS variables, even when the variable depends on other variables (#1630950)
We also display the computed value in the input autocomplete (#1911524)
Display empty CSS variable value as <empty> , in the variable tooltip and in the computed panel, so it stands out (#1912267, #1912268)
Nicolas fixed a crash in the Rules view that was happening when the page was using a particular declaration value (e.g. (max-width: 10px)) (#1915353)
Julian made it possible to change css values with mouse scroll when hovering a numeric value in the input (#1801545)
Julian fixed an annoying issue that forced users to disconnect and reconnect the device when remote debugging Android WebExtensions (#1856481)
Still in WebExtension land, Julian got rid of a bug where breakpoints could still be triggered after being deleted (#1908095)
Alex Thayer Implemented a native backend for the JS tracer which will make tracing much faster (#1906719)
Alexandre made it possible to show function arguments in tracer popup previews (#1909548)
Julian fixed a couple issues in the Inspector node picker: picking a video would play/pause said video (#1913263), and also, the NodePicker randomly stopped working after cancelled navigation from about:newtab (#1914863)
WebDriver BiDi
External:
Gatlin Newhouse updated mozrunner to search for DevEdition when running on macos (#1909999)
Dan implemented 2 enhancements for our WebDriver BiDi codebase:
Added an emitEventForBrowsingContext method which is useful for most of our root BiDi modules (#1859328)
Updates:
Julian updated the vendored version of Puppeteer to v23.1.0, which is one of the first releases to officially support Firefox. This should also fix a nasty side effect which could wipe your files when running ./mach puppeteer-test (#1912239 and 1911968)
Geckodriver 0.35.0 was released with support for Permissions, a flag to enable the crash reporter, and improvements for the unhandledPromptBehavior capability. (#1871543, blog post)
James fixed a bug with input.KeyDownAction and input.keyUpAction which would unexpectedly accept multiple characters (#1910352)
Sasha updated the browsingContext.navigate command to properly fail with “unknown error” when the navigation failed (#1905083)
Sasha fixed a bug where WebDriver BiDi session.new would return an invalid value for the default unhandledPromptBehavior capability. (#1909455)
Julian added support to all the remaining arguments for network.continueResponse, which can now update cookies, headers, statusCode and reasonPhrase of a real network response intercepted in the responseStarted phase (which roughly corresponds to the http-on-examine-response notification) (#1913737 + #1853887)
Errors and Critical issues are now being raised as errors (previously they weren’t being considered).
More warnings will now be “fatal”, all the existing instances of those warnings have been eliminated. They’ll now be listed in as a specific failure rather than being hidden in the list of general warnings.
Some of the warnings that were being output by the generate CI task have now been resolved, which should make it clearer when trying to understand the failures.
Migration Improvements
fchasen is working on a new messaging experiment to help encourage people to create accounts to help facilitate device migration / data transfer. QA has come back green, and we expect to begin enrollment soon!
New Tab Page
Scott (:thecount) is working on a plan to transition us off the two separate endpoints that provide firesponsored stories and top sites to New Tab to a single end-point.
A new mechanism to let users specify the kinds of stories they are interested in with “thumbs up” / “thumbs down” feedback is being experimented with. We’ll be studying this during the Firefox 130 cycle.
We’re (slowly) rolling out a new endpoint for recommended stories to New Tab, powered by Merino. The goal is to eventually allow us to better serve specific content topics that users will be able to choose. This is early days, and still being experimented with – but the new endpoint will make things much simpler for us.
(Note: to avoid potentially breaking the world for nightly users, this work is currently behind the MOZ_SELECTABLE_PROFILES build flag and the browser.profiles.enabled pref.)
Mossop removed the –no-remote command line argument and MOZ_NO_REMOTE environment variable, so that the remoting server will always be enabled in a running instance of Firefox (bug 1906260)
Mossop updated the remoting service to support sending command lines after startup (bug 1892400). We’ll use this to broadcast updates across concurrently running instances whenever one of them updates the profile group’s shared SQLite datastore.
Niklas landed a change to update the default Firefox profile to the last used (last app focused) profile if multiple profiles in a group are running at the same time (bug 1893710)
Jared added support for launching selectable profiles (or any unmanaged profiles not in profiles.ini) using the –profile command line option (bug 1910716). This enables launching selectable profiles from UI clicks.
Jared updated the startup sequence to allow starting into new the profile selector window (bug 1893667)
Search and Navigation
Scotch Bonnet redesign
James improved support for persisting search terms when the feature is enabled – Bug 1901871, Bug 1909301
Karandeep implemented updating the unified button icon when the default search engine changes – Bug 1906054
James fixed a bug causing 2 search engine chiclets to show in the address bar at the same time – Bug 1911777
We’re back for an update on Thunderbird for Android/K-9 Mail, combining progress reports for July and August. Did you miss our June update? Check it out! The focus over these two months has been on quality over quantity—behind each improvement is significant groundwork that reduces our technical debt and makes future feature work easier to tackle.
Material 3 Update
As we head towards the release of Thunderbird for Android, we want you to feel like you are using Thunderbird, and not just any email client. As part of that, we’ve made significant strides toward compatibility with Material 3 to better control coloring and give you a native feel. What do you think so far?
The final missing piece is the navigation drawer, which we believe will land in September. We’ve heard your feedback that the unread emails have been a bit hard to see, especially in dark mode, and have made a few other color tweaks to accompany it.
Feature Modules
If you’ve considered contributing as a developer to Thunderbird for Android, you may have noticed many intertwined code modules that are hard to tackle without intricate knowledge of the application. To lower the barrier of entry, we’re continuing the move to a feature module system and have been refactoring code to use them. This shift improves maintainability and opens the door for unique features specific to Thunderbird for Android.
Ready to Play
Having a separate Thunderbird for Android app requires some setup in various app-stores, as well as changes to how apps are signed. While this isn’t the fun feature work you’d be excited to hear about, it is foundational to getting Thunderbird for Android out of the door. We’re almost ready to play, just a few legal checkboxes we need to tick.
Documentation
K-9 Mail user documentation has become outdated, still referencing older versions like K-9 Mail 6.4. Given our current resources, we’ve paused updates to the guide, but if you’re passionate about improving documentation, we’d love your help to bring it back online! If you are interested in maintaining our user documentation, please reach out on the K-9 Forums.
Community Contributions
We’ve had a bunch of great contributions come in! Do you want to see your name here next time? Learn how to contribute.
I’m Bryan Thrall, just passing two and a half years on the SpiderMonkey team, and taking a try at newsletter writing.
This is our opportunity to highlight what’s happened in the world of SpiderMonkey over Firefox releases 130 and 131.
I’d love to hear any feedback on the newsletter you have, positive or negative (you won’t hurt my feelings). Send it to my email!
🚀 Performance
Though Speedometer 3 has shipped, we cannot allow that to let us get lax with our performance. It’s important that SpiderMonkey be fast so Firefox can be fast!
Contributor Andre Bargull (@anba) added JIT support for Float16Array (bug 1835034)
⚡ Wasm
Ryan (@rhunt) implemented speculative inlining (bug 1910194)*. This allows us to inline calls based on profiling data in wasm
Julian (@jseward) added support for direct call inlining in Ion (bug 1868521)*
Ryan (@rhunt) landed initial support for lazy tiering (bug 1905716)*
Ryan (@rhunt) shipped exnref support (bug 1908375)
Yury (@yury) added JS Promise Integration support for x86-32 and ARM (bug 1896218, bug 1897153)*
* Disabled by default while they are tested and refined.
Andre Bargull (@anba) also implemented the RegExp.escape proposal (bug 1911097)
Contributor Kiril K (@kirill.kuts.dev) implemented the Regular Expression Pattern Modifiers proposal (bug 1899813)
Dan (@dminor) shipped synchronous Iterator Helpers (bug 1896390)
👷🏽♀️ SpiderMonkey Platform Improvements
Matt (@mgaudet) introduced JS_LOG, which connects to MOZ_LOG when building SpiderMonkey with Gecko (bug 1904429). This will eventually allow collecting SpiderMonkey logs from the profiler and about:logging.
The 0.4.0 release of uv
does everything I currently do with pip, pyenv, pipx, pip-tools, and
pipdeptree. Because of that, I'm in the process of switching to uv.
This blog post covers switching from pyenv to uv.
History
2024-08-29: Initial writing.
2024-09-12: Minor updates and publishing.
2024-09-20: Rename uv-sync (which is confusing) to uv-python-symlink.
Start state
I'm running Ubuntu Linux 24.04. I have pyenv installed using the
the automatic installer.
pyenv is located in $HOME/.pyenv/bin/.
I have the following Pythons installed with pyenv:
$ pyenv versions
system
3.7.17
3.8.19
3.9.19
* 3.10.14 (set by /home/willkg/mozilla/everett/.python-version)3.11.9
3.12.3
I'm not sure why I have 3.7 still installed. I don't think I use that for
anything.
My default version is 3.10.14 for some reason. I'm not sure why I haven't
updated that to 3.12, yet.
In my 3.10.14, I have the following Python packages installed:
When I type "python", I want it to be a Python managed by uv. Also, I like
having "pythonX.Y" symlinks, so I created a uv-python-symlink-sync script
which creates symlinks to uv-managed Python versions:
Then I installed all my tools using uv tool install.
$ uv tool install PACKAGE
For tox, I had to install the tox-uv package in the tox
environment:
$ uv tool install --with tox-uv tox
Now I've got everything I do mostly working.
So what does that give me?
I installed uv and I can upgrade uv using uv self update.
Python interpreters are managed using uv python. I can create symlinks to
interpreters using uv-sync script. Adding new interpreters and removing old
ones is pretty straight-forward.
When I type python, it opens up a Python shell with the latest uv-managed
Python version. I can type pythonX.Y and get specific shells.
I can use tools written in Python and manage them with uv tool including
ones where I want to install them in an "editable" mode.
I can write scripts that require dependencies and it's a lot easier to run them
now.
I can create and manage virtual environments with uv venv.
Next steps
Delete all the .python-version files I've got.
Update documentation for my projects and add a uv tool install PACKAGE
option to installation instructions.
Probably discover some additional things to add to this doc.
Thanks
Thank you to the Astral crew who wrote uv.
Thank you to Rob Hudson who goaded me into posting this finally rather than sit
on it another month.

As a web engine, Servo primarily handles everything around scripting and layout.
For embedding use cases, the Tauri community experimented with adding a new Servo backend, but Servo can also be used to build a browser.
We have a reference browser in the form of servoshell, which has historically been used as a minimal example and as a test harness for the Web Platform Tests.
Nevertheless, the Servo community has steadily worked towards making it a browser in its own right, starting with our new browser UI based on egui last year.
This year, @wusyong, a member of Servo TSC, created the Verso project as a way to explore the features Servo needs to power a robust web browser.
In this post, we’ll explain what we tried to achieve, what we found, and what’s next for building a browser using Servo as a web engine.
Multi-view
Of course, the first major feature we want to achieve is multiple webviews.
A webview is a term abstracted from the top-level browsing context.
This is what people refer to as a web page.
With multi-view support, we can create multiple web pages as tabs in a single window.
Most importantly, we can draw our UI with additional webviews.
The main reason we want to write UI using Servo itself is that we can dogfood our own stack and verify that it can meet practical requirements, such as prompt windows, context menus, file selectors, and more.
Basic multi-view support was reviewed and merged into Servo earlier this year thanks to @delan (#30840, #30841, #30842).
Verso refined that into a specific type called WebView.
From there, any function that owns webviews can decide how to present them depending on their IDs.
In a Verso window, two webviews are created at the moment—one for handling regular web pages and the other for handling the UI, which is currently called the Panel.
The result of the showcase in Verso’s README.md looks like this:
<figcaption>Figure 1: Verso window displaying two different webviews. One for the UI, the other for the web page.</figcaption>
For now, the inter-process communication is done via Servo’s existing channel messages like EmbedderMsg and EmbedderEvent.
We are looking to improve the IPC mechanism with more granular control over DOM elements.
So, the panel UI can be updated based on the status of web pages.
One example is when the page URL is changed and the navigation bar needs to be updated.
There are some candidates for this, such as WebDriverCommandMsg.
@webbeef also started a discussion about defining custom elements like <webview> for better ergonomics.
Overall, improving IPC will be the next target to research after initial multi-view support.
We will also define more specific webview types to satisfy different purposes in the future.
Multi-window
The other prominent feature after multi-view is the ability to support multiple windows.
This one wasn’t planned at first, but because it affects too many components, we ended up resolving them together from the ground up.
Servo uses WebRender, based on OpenGL, to render its layout.
To support multiple windows, we need to support multiple OpenGL surfaces.
One approach would be to create separate OpenGL contexts for each window.
But since our implementations of WebGL, WebGPU, and WebXR are all tied to a single WebRender instance, which in turn only supports a single OpenGL context for now, we chose to use a single context with multiple surfaces.
This alternative approach could potentially use less memory and spawn fewer threads.
For more details, see this series of blog posts by @wusyong.
<figcaption>Figure 2: Verso creates two separate windows with the same OpenGL context.</figcaption>
There is still room for improvement.
For example, WebRender currently only supports rendering a single “document”.
Unless we create multiple WebRender instances, like Firefox does, we have one WebRender document that has to constantly update all of its display lists to show on all of our windows.
This could potentially lead to race conditions where a webview may draw to the wrong window for a split second.
There are also different OpenGL versions across multiple platforms, which can be challenging to configure and link.
Verso is experimenting with using Glutin for better configuration and attempting to get closer to the general Rust ecosystem.
What’s next?
With multi-view and multi-window support as the fundamental building blocks, we could create more UI elements to keep pushing the envelope of our browser and embedding research.
At the same time, Servo is a huge project, with many potential improvements still to come, so we want to reflect on our progress and decide on our priorities.
Here are some directions that are worth pursuing.
Benchmarking and metrics
We want to gather the strength of the community to help us track the statistics of supported CSS properties and web APIs in Servo by popularity order and benchmark results such as jetstream2 and speedometer3.
@sagudev already started a subset of speedometer3 to experiment.
We hope this will eventually give newcomers a better overview of Servo.
Script triage
There’s a Servo triage meeting every two weeks to triage any issues around the script crate and more.
Once we get the statistics of supported web APIs, we can find the most popular ones that haven’t been implemented or fixed yet.
We are already fixing some issues around loading the order and re-implementing ReadableStream in Rust.
If you are interested in implementing web APIs in Servo, feel free to join the next meeting.
Multi-process and sandboxing
Some features are crucial to the browser but not visible to users.
Multi-process architecture and sandboxing belong to this category.
Both of these are implemented in Servo to some extent, but only on Linux and macOS right now, and neither of the features are enabled by default.
We would like to improve these features and validate them in CI workflows.
In the meantime, we are looking for people who can extend our sandbox to Windows via Named Pipes and AppContainer Isolation.
Many of us Thunderbird users often forget just how convenient using a mail client can be. But as webmail has become more popular over the last decade, some new users might not know the difference between the two, and why you would want to swap your browser for a dedicated app.
In today’s digital world, email remains a cornerstone of personal and professional communication. Managing emails, however, can be a daunting task especially when you have multiple email accounts with multiple service providers to check and keep track of. Thankfully, decades ago someone invented the email client application. While web-based solutions have taken off in recent years, they can’t quite replace the need for managing emails in one dedicated place.
Let’s go back to the basics: What is the difference between an email service provider and an email client application? And more importantly, can we make a compelling case for why an email client like Thunderbird is not just relevant in today’s world, but essential in maintaining productivity and sanity in our fast-paced lives?
An email service provider (ESP) is a company that offers services for sending, receiving, and storing emails. Popular examples include Gmail, Yahoo Mail, Hotmail and Proton Mail. These services offer web-based interfaces, allowing users to access their emails from any device with an internet connection.
On the other hand, an email client application is software installed on your device that allows you to manage any or all of those email accounts in one dedicated app. Examples include Thunderbird, Microsoft Outlook, and Apple Mail. Email clients offer a unified platform to access multiple email accounts, calendars, tasks, and contacts, all in one place. They retrieve emails from your ESP using protocols like IMAP or POP3 and provide advanced features for organizing, searching, and composing emails.
Despite the convenience of web-based email services, email client applications play a huge role in enhancing productivity and efficiency. Webmail is a juggling game of switching tabs, logins, and sometimes wildly different interfaces. This fragmented approach can steal your time and your focus.
So, how can an email client help with all of that?
One Inbox – All Your Accounts
As already mentioned, an email client eliminates the need to switch between different browser tabs or sign in and out of accounts. Combine your Gmail, Yahoo, and other accounts so you can read, reply to, and search through the emails using a single application. For even greater convenience, you can opt for a unified inbox view, where emails from all your different accounts are combined into a single inbox.
Work Offline – Anywhere
Email clients store your emails locally on your device, so you can access and compose emails even without an internet connection. This is really useful when you’re travelling or in areas with poor connectivity. You can draft responses, organize your inbox, and synchronize your changes once you’re back online.
Enhanced Productivity
Email clients come packed with features designed to boost productivity. These include advanced search capabilities across multiple accounts, customizable filters and rules, as well as integration with calendar and task management tools. Features like email templates and delayed sending can streamline your workflow even more.
Care About Privacy?
Email clients offer enhanced security features, such as encryption and digital signatures, to protect your sensitive information. With local storage, you have more control over your data compared to relying solely on a web-based ESP.
No More Clutter and Distractions
Web-based email services often come with ads, sometimes disguised as emails, and other distractions. Email clients, on the other hand, provide a cleaner ad-free experience. It’s just easier to focus with a dedicated application just for email. Not having to reply on a browser for this purpose means less chance of getting sidetracked by latest news, social media, and random Google searches.
All Your Calendars in One Place
Last but not least, managing your calendar, or multiple calendars, is easier with an email client. You can sync calendars from various accounts, set reminders, and schedule meetings all in one place. This is particularly useful when handling calendar invites from different accounts, as it allows you to easily shift meetings between calendars or maintain one main calendar to avoid double booking.
So, if you’re not already using an email client, perhaps this post has given you a few good reasons to at least try it out. An email client can help you organize your busy digital life, keep all your email and calendar accounts in one place, and even draft emails during your next transatlantic flight with non-existent or questionable Wi-Fi.
And just as email itself has evolved over the past decades, so have email client applications. They’ll adapt to modern trends and get enhanced with the latest features and integrations to keep everyone organized and productive – in 2024 and beyond.
Generative AI’s Illusory Case for Fair Use by Jacqueline Charlesworth :: SSRN The exploitation of copied works for their intrinsic expressive value sharply distinguishes AI copying from that at issue in the technological fair use cases relied upon by AI’s fair use advocates. In these earlier cases, the determination of fair use turned on the fact that the alleged infringer was not seeking to capitalize on expressive content-exactly the opposite of generative AI.
Copyright lawsuits pose a serious threat to generative AIThe core question in fair use analysis is whether a new product acts as a substitute for the product being copied, or whether it transforms the old product into something new and distinctive. In the Google Books case, for example, the courts had no trouble finding that a book search engine was a new, transformative product that didn’t in any way compete with the books it was indexing. Google wasn’t making new books. Stable Diffusion is creating new images. And while Google could guarantee that its search engine would never display more than three lines of text from any page in a book. Stability AI can’t make a similar promise. To the contrary, we know that Stable Diffusion occasionally generates near-perfect copies of images from its training data.

Is AI a Silver Bullet? — Ian Cooper - Staccato SignalsTDD becomes a powerful tool when you ask the AI to implement code for your tests (TDD is already a powerful tool, and LLMs could be a good force multiplier. Not just writing code that you can filter the bullshit out of by adding tests, but also by suggesting tests that your code should be able to pass. If the LLM outputs a test that obviously shouldn’t pass but does, then you can fix your code sooner. If I had to guess I would say that programming language advocacy scenes are going to figure out the licensing for training sets first. If the coding assistant in the IDE can train on zillions of lines of a certain language because of a programmer co-op agreement, that’s an advantage for the language.)
Have we stopped to think about what LLMs actually model?Big corporations like Meta and Google tend to exaggerate and make misleading claims that do not stand up to scrutiny. Obviously, as a cognitive scientist who has the expertise and understanding of human language, it’s disheartening to see a lot of these claims made without proper evidence to back them up. But they also have downstream impacts in various domains. If you start treating these massive complex engineering systems as language understanding machines, it has implications in how policymakers and regulators think about them.
Slop is GoodSearch engines you can’t trust because they are cesspools of slop is hard to imagine. But that end feels inevitable at this point. We will need a new web. (I tend to agree with this. Search engine company management tends to be so ideologically committed to busting the search quality raters union, and other labor organizing by indirect employees, or TVCs, that they will destroy the value of the search engine to do it.)
The Rust team is happy to announce a new version of Rust, 1.81.0. Rust is a programming language empowering everyone to build reliable and efficient software.
If you have a previous version of Rust installed via rustup, you can get 1.81.0 with:
If you'd like to help us out by testing future releases, you might consider updating locally to use the beta channel (rustup default beta) or the nightly channel (rustup default nightly). Please report any bugs you might come across!
What's in 1.81.0 stable
core::error::Error
1.81 stabilizes the Error trait in core, allowing usage of the trait in
#![no_std] libraries. This primarily enables the wider Rust ecosystem to
standardize on the same Error trait, regardless of what environments the
library targets.
New sort implementations
Both the stable and unstable sort implementations in the standard library have
been updated to new algorithms, improving their runtime performance and
compilation time.
Additionally, both of the new sort algorithms try to detect incorrect
implementations of Ord that prevent them from being able to produce a
meaningfully sorted result, and will now panic on such cases rather than
returning effectively randomly arranged data. Users encountering these panics
should audit their ordering implementations to ensure they satisfy the
requirements documented in PartialOrd and Ord.
#[expect(lint)]
1.81 stabilizes a new lint level, expect, which allows explicitly noting that
a particular lint should occur, and warning if it doesn't. The intended use
case for this is temporarily silencing a lint, whether due to lint
implementation bugs or ongoing refactoring, while wanting to know when the lint
is no longer required.
For example, if you're moving a code base to comply with a new restriction
enforced via a Clippy lint like
undocumented_unsafe_blocks,
you can use #[expect(clippy::undocumented_unsafe_blocks)] as you transition,
ensuring that once all unsafe blocks are documented you can opt into denying
the lint to enforce it.
Clippy also has two lints to enforce the usage of this feature and help with
migrating existing attributes:
clippy::allow_attributes to restrict allow attributes in favor of #[expect] or to migrate #[allow] attributes to #[expect]
Changing the lint level is often done for some particular reason. For example,
if code runs in an environment without floating point support, you could use
Clippy to lint on such usage with #![deny(clippy::float_arithmetic)].
However, if a new developer to the project sees this lint fire, they need to
look for (hopefully) a comment on the deny explaining why it was added. With
Rust 1.81, they can be informed directly in the compiler message:
error: floating-point arithmetic detected
--> src/lib.rs:4:5
|
4 | a + b
| ^^^^^
|
= help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#float_arithmetic
= note: no hardware float support
note: the lint level is defined here
--> src/lib.rs:1:9
|
1 | #![deny(clippy::float_arithmetic, reason = "no hardware float support")]
| ^^^^^^^^^^^^^^^^^^^^^^^^
core::panic::PanicInfo will remain unchanged, however, as this is now a
different type.
The reason is that these types have different roles:
std::panic::PanicHookInfo is the argument to the panic hook in std
context (where panics can have an arbitrary payload), while
core::panic::PanicInfo is the argument to the
#[panic_handler] in
#![no_std] context (where panics always carry a formatted message). Separating
these types allows us to add more useful methods to these types, such as
std::panic::PanicHookInfo::payload_as_str() and
core::panic::PanicInfo::message().
Abort on uncaught panics in extern "C" functions
This completes the transition started in 1.71,
which added dedicated "C-unwind" (amongst other -unwind variants) ABIs for
when unwinding across the ABI boundary is expected. As of 1.81, the non-unwind
ABIs (e.g., "C") will now abort on uncaught unwinds, closing the longstanding
soundness problem.
Programs relying on unwinding should transition to using -unwind suffixed ABI
variants.
WASI 0.1 target naming changed
Usage of the wasm32-wasi target (which targets WASI 0.1) will now issue a
compiler warning and request users switch to the wasm32-wasip1 target
instead. Both targets are the same, wasm32-wasi is only being renamed, and
this change to the WASI target
is being done to enable removing wasm32-wasi in January 2025.
Fixes CVE-2024-43402
std::process::Command now correctly escapes arguments when invoking batch
files on Windows in the presence of trailing whitespace or periods (which are
ignored and stripped by Windows).
The default way impl Trait works in return position is changing in Rust 2024. These changes are meant to simplify impl Trait to better match what people want most of the time. We're also adding a flexible syntax that gives you full control when you need it.
TL;DR
Starting in Rust 2024, we are changing the rules for when a generic parameter can be used in the hidden type of a return-position impl Trait:
a new default that the hidden types for a return-position impl Trait can use any generic parameter in scope, instead of only types (applicable only in Rust 2024);
a syntax to declare explicitly what types may be used (usable in any edition).
The new explicit syntax is called a "use bound": impl Trait + use<'x, T>, for example, would indicate that the hidden type is allowed to use 'x and T (but not any other generic parameters in scope).
Read on for the details!
Background: return-position impl Trait
This blog post concerns return-position impl Trait, such as the following example:
The use of -> impl Iterator in return position here means that the function returns "some kind of iterator". The actual type will be determined by the compiler based on the function body. It is called the "hidden type" because callers do not get to know exactly what it is; they have to code against the Iterator trait. However, at code generation time, the compiler will generate code based on the actual precise type, which ensures that callers are fully optimized.
Although callers don't know the exact type, they do need to know that it will continue to borrow the data argument so that they can ensure that the data reference remains valid while iteration occurs. Further, callers must be able to figure this out based solely on the type signature, without looking at the function body.
Rust's current rules are that a return-position impl Trait value can only use a reference if the lifetime of that reference appears in the impl Trait itself. In this example, impl Iterator<Item = ProcessedDatum> does not reference any lifetimes, and therefore capturing data is illegal. You can see this for yourself on the playground.
The error message ("hidden type captures lifetime") you get in this scenario is not the most intuitive, but it does come with a useful suggestion for how to fix it:
help: to declare that
`impl Iterator<Item = ProcessedDatum>`
captures `'_`, you can add an
explicit `'_` lifetime bound
|
5 | ) -> impl Iterator<Item = ProcessedDatum> + '_ {
| ++++
Following a slightly more explicit version of this advice, the function signature becomes:
fn process_data<'d>(
data: &'d [Datum]
) -> impl Iterator<Item = ProcessedDatum> + 'd {
data
.iter()
.map(|datum| datum.process())
}
In this version, the lifetime 'd of the data is explicitly referenced in the impl Trait type, and so it is allowed to be used. This is also a signal to the caller that the borrow for data must last as long as the iterator is in use, which means that it (correctly) flags an error in an example like this (try it on the playground):
let mut data: Vec<Datum> = vec![Datum::default()];
let iter = process_data(&data);
data.push(Datum::default()); // <-- Error!
iter.next();
Usability problems with this design
The rules for what generic parameters can be used in an impl Trait were decided early on based on a limited set of examples. Over time we have noticed a number of problems with them.
not the right default
Surveys of major codebases (both the compiler and crates on crates.io) found that the vast majority of return-position impl trait values need to use lifetimes, so the default behavior of not capturing is not helpful.
not sufficiently flexible
The current rule is that return-position impl trait always allows using type parameters and sometimes allows using lifetime parameters (if they appear in the bounds). As noted above, this default is wrong because most functions actually DO want their return type to be allowed to use lifetime parameters: that at least has a workaround (modulo some details we'll note below). But the default is also wrong because some functions want to explicitly state that they do NOT use type parameters in the return type, and there is no way to override that right now. The original intention was that type alias impl trait would solve this use case, but that would be a very non-ergonomic solution (and stabilizing type alias impl trait is taking longer than anticipated due to other complications).
hard to explain
Because the defaults are wrong, these errors are encountered by users fairly regularly, and yet they are also subtle and hard to explain (as evidenced by this post!). Adding the compiler hint to suggest + '_ helps, but it's not great that users have to follow a hint they don't fully understand.
incorrect suggestion
Adding a + '_ argument to impl Trait may be confusing, but it's not terribly difficult. Unfortunately, it's often the wrong annotation, leading to unnecessary compiler errors -- and the right fix is either complex or sometimes not even possible. Consider an example like this:
Here the process function applies context.process to each of the elements in data (of type T). Because the return value uses context, it is declared as + 'c. Our real goal here is to allow the return type to use 'c; writing + 'c achieves that goal because 'c now appears in the bound listing. However, while writing + 'c is a convenient way to make 'c appear in the bounds, also means that the hidden type must outlive 'c. This requirement is not needed and will in fact lead to a compilation error in this example (try it on the playground).
The reason that this error occurs is a bit subtle. The hidden type is an iterator type based on the result of data.into_iter(), which will include the type T. Because of the + 'c bound, the hidden type must outlive 'c, which in turn means that T must outlive 'c. But T is a generic parameter, so the compiler requires a where-clause like where T: 'c. This where-clause means "it is safe to create a reference with lifetime 'c to the type T". But in fact we don't create any such reference, so the where-clause should not be needed. It is only needed because we used the convenient-but-sometimes-incorrect workaround of adding + 'c to the bounds of our impl Trait.
Just as before, this error is obscure, touching on the more complex aspects of Rust's type system. Unlike before, there is no easy fix! This problem in fact occurred frequently in the compiler, leading to an obscure workaround called the Captures trait. Gross!
We surveyed crates on crates.io and found that the vast majority of cases involving return-position impl trait and generics had bounds that were too strong and which could lead to unnecessary errors (though often they were used in simple ways that didn't trigger an error).
inconsistencies with other parts of Rust
The current design was also introducing inconsistencies with other parts of Rust.
async fn desugaring
Rust defines an async fn as desugaring to a normal fn that returns -> impl Future. You might therefore expect that a function like process:
In practice, because of the problems with the rules around which lifetimes can be used, this is not the actual desugaring. The actual desugaring is to a special kind of impl Trait that is allowed to use all lifetimes. But that form of impl Trait was not exposed to end-users.
impl trait in traits
As we pursued the design for impl trait in traits (RFC 3425), we encountered a number of challenges related to the capturing of lifetimes. In order to get the symmetries that we wanted to work (e.g., that one can write -> impl Future in a trait and impl with the expected effect), we had to change the rules to allow hidden types to use all generic parameters (type and lifetime) uniformly.
Rust 2024 design
The above problems motivated us to take a new approach in Rust 2024. The approach is a combination of two things:
a new default that the hidden types for a return-position impl Trait can use any generic parameter in scope, instead of only types (applicable only in Rust 2024);
a syntax to declare explicitly what types may be used (usable in any edition).
The new explicit syntax is called a "use bound": impl Trait + use<'x, T>, for example, would indicate that the hidden type is allowed to use 'x and T (but not any other generic parameters in scope).
Lifetimes can now be used by default
In Rust 2024, the default is that the hidden type for a return-position impl Trait values use any generic parameter that is in scope, whether it is a type or a lifetime. This means that the initial example of this blog post will compile just fine in Rust 2024 (try it yourself by setting the Edition in the Playground to 2024):
Impl Traits can include a use<> bound to specify precisely which generic types and lifetimes they use
As a side-effect of this change, if you move code to Rust 2024 by hand (without cargo fix), you may start getting errors in the callers of functions with an impl Trait return type. This is because those impl Trait types are now assumed to potentially use input lifetimes and not only types. To control this, you can use the new use<> bound syntax that explicitly declares what generic parameters can be used by the hidden type. Our experience porting the compiler suggests that it is very rare to need changes -- most code actually works better with the new default.
The exception to the above is when the function takes in a reference parameter that is only used to read values and doesn't get included in the return value. One such example is the following function indices(): it takes in a slice of type &[T] but the only thing it does is read the length, which is used to create an iterator. The slice itself is not needed in the return value:
In Rust 2021, this declaration implicitly says that slice is not used in the return type. But in Rust 2024, the default is the opposite. That means that callers like this will stop compiling in Rust 2024, since they now assume that data is borrowed until iteration completes:
fn main() {
let mut data = vec![1, 2, 3];
let i = indices(&data);
data.push(4); // <-- Error!
i.next(); // <-- assumed to access `&data`
}
This may actually be what you want! It means you can modify the definition of indices() later so that it actually does include slice in the result. Put another way, the new default continues the impl Trait tradition of retaining flexibility for the function to change its implementation without breaking callers.
But what if it's not what you want? What if you want to guarantee that indices() will not retain a reference to its argument slice in its return value? You now do that by including a use<> bound in the return type to say explicitly which generic parameters may be included in the return type.
In the case of indices(), the return type actually uses none of the generics, so we would ideally write use<>:
fn indices<'s, T>(
slice: &'s [T],
) -> impl Iterator<Item = usize> + use<> {
// -----
// Return type does not use `'s` or `T`
0 .. slice.len()
}
Implementation limitation. Unfortunately, if you actually try the above example on nightly today, you'll see that it doesn't compile (try it for yourself). That's because use<> bounds have only partially been implemented: currently, they must always include at least the type parameters. This corresponds to the limitations of impl Trait in earlier editions, which always must capture type parameters. In this case, that means we can write the following, which also avoids the compilation error, but is still more conservative than necessary (try it yourself):
This implementation limitation is only temporary and will hopefully be lifted soon! You can follow the current status at tracking issue #130031.
Alternative: 'static bounds. For the special case of capturing no references at all, it is also possible to use a 'static bound, like so (try it yourself):
fn indices<'s, T>(
slice: &'s [T],
) -> impl Iterator<Item = usize> + 'static {
// -------
// Return type does not capture references.
0 .. slice.len()
}
'static bounds are convenient in this case, particularly given the current implementation limitations around use<> bounds, but use<> bound are more flexible overall, and so we expect them to be used more often. (As an example, the compiler has a variant of indices that returns newtype'd indices I instead of usize values, and it therefore includes a use<I> declaration.)
Conclusion
This example demonstrates the way that editions can help us to remove complexity from Rust. In Rust 2021, the default rules for when lifetime parameters can be used in impl Trait had not aged well. They frequently didn't express what users needed and led to obscure workarounds being required. They led to other inconsistencies, such as between -> impl Future and async fn, or between the semantics of return-position impl Trait in top-level functions and trait functions.
Thanks to editions, we are able to address that without breaking existing code. With the newer rules coming in Rust 2024,
most code will "just work" in Rust 2024, avoiding confusing errors;
for the code where annotations are required, we now have a more powerful annotation mechanism that can let you say exactly what you need to say.
Appendix: Relevant links
Precise capture was proposed in RFC #3617, which left an unresolved question regarding syntax, and its tracking issue was #123432.
The unresolved syntax question was resolved in issue #125836, which introduced the + use<> notation used in this post.
The implementation limitation is tracked in #130031.
Note: This blog post was written on June 2024. As of September 2024, final work to ship the feature is still in progress. Please follow bug 1797715 for the latest updates.
Introduction
This is the final blog post in a series about new web platform features implemented in Gecko, as part as an effort at Igalia to increase browser interoperability.
Let’s take a look at fetch priority attributes, which enable web developers to optimize resource loading by specifying the relative priority of resources to be fetched by the browser.
Fetch priority
The web.dev article on fetch priority explains in more detail how web developers can use fetch priority to optimize resource loading, but here’s a quick overview.
fetchpriority is a new attribute with the value auto (default behavior), high, or low.
Setting the attribute on a script, link or img element indicates whether the corresponding resource should be loaded with normal, higher, or lower priority 1:
103 Early Hint
Link: <high.js>; rel=preload; as=script; fetchpriority=high
These are basically all the places where a fetch priority attribute can be used.
Note that other parameters are also taken into account when deciding the priority to use for resources, such as the position of the element in the page (e.g. blocking resources in <head>), other attributes on the element (<script async>, <script defer>, <link media>, <link rel>…) or the resource’s destination.
Finally, some browsers implement speculative HTML parsing, allowing them to continue fetching resources declared in the HTML markup while the parser is blocked.
As far as I understand, Firefox has its own separate HTML parsing code for that purpose, which also has to take fetch priority attributes into account.
Implementation-defined prioritization
If you have not run away after reading the complexity described in the previous section, let’s talk a bit more about how fetch priority attributes are interpreted.
The spec contains the following step when fetching a resource (emphasis mine):
If request’s internal priority is null, then use request’s priority, initiator, destination, and render-blocking in an implementation-defined manner to set request’s internal priority to an implementation-defined object.
So browsers would use the high/low/auto hints as well as the destination in order to calculate an internal priority value 3, but the details of this value are not provided in the specification, and it’s up to the browser to decide what to do.
This is a bit unfortunate for our interoperability goal, but that’s probably the best we can do, given that each browser already has its own stategies to optimize resource loading.
I think this also gives browsers some flexibility to experiment with optimizations… which can be hard to predict when you realize that web devs also try to adapt their content to the behavior of (the most popular) browsers!
In any case, the spec authors were kind enough to provide a note with more suggestions (emphasis mine):
The implementation-defined object could encompass stream weight and dependency for HTTP/2, priorities used in Extensible Prioritization Scheme for HTTP for transports where it applies (including HTTP/3), and equivalent information used to prioritize dispatch and processing of HTTP/1 fetches. [RFC9218]
OK, so what does that mean?
I’m not a networking expert, but this is what I could gather after discussing with the Necko team and reading some HTTP specs:
HTTP/1 does not have a dedicated prioritization mechanism, but Firefox uses its internal priority to order requests.
HTTP/2 has a “stream priority” mechanism and Firefox uses its internal priority to implement that part of the spec.
However, it was considered too complex and inefficient, and is likely poorly supported by existing web servers…
In upcoming releases, Firefox will use its internal priority to implement the Extensible Prioritization Scheme used by HTTP/2 and HTTP/3.
See bug 1865040 and bug 1864392.
Essentially, this means using its internal priority to adjust the urgency parameter.
Note that various parts of Firefox rely on NS_NewChannel to load resources, including the fetching algorithm above, which Firefox uses to implement the fetch() method.
However, other cases mentioned in the first section have their own code paths with their own calls to NS_NewChannel, so these places must also be adjusted to take the fetch priority and destination into account.
Adding fetchpriority to DOM objects for HTMLImageElement, HTMLLinkElement, HTMLScriptElement, and RequestInit.
Parsing the fetch priority attribute into an auto/low/high enum.
Passing the information to the callers of NS_NewChannel.
Using that information to set the internal priority.
Using that internal priority for HTTP requests.
Mirko Brodesser started this work in June 2023, and had already implemented almost all of the features discussed above.
fetch(), <img>, and <link rel=preload as=image> were handled by Ziran Sun and I, while Valentin Gosu from Mozilla made HTTP requests use the internal priority.
The main blocker was due to that “implementation-defined” use of fetch priority.
Mirko’s approach was to align Firefox with the behavior described in the web.dev article, which reflects Chromium’s implementation.
But doing so would mean changing Firefox’s default behavior when fetchpriority is not specified (or explicitly set to auto), and it was not clear whether Chromium’s prioritization choices were the best fit for Firefox’s own implementation of resource loading.
After meeting with Mozilla, we agreed on a safer approach:
Introduce runtime preferences to control how Firefox adjusts internal priorities when low, high, or auto is specified.
By default, auto does not affect the internal priority so current behavior is preserved.
Ask Mozilla’s performance team to run an experiment, so we can decide the best values for these preferences.
Ship fetch priority with the chosen values, probably cleaning things up a bit.
Any other ideas, including the ones described in the web.dev article, could be handled in future enhancements.
We recently entered phase 2 of this plan, so fingers crossed it works as expected!
Internal WPT tests
This project is part of the interoperability effort, but again, the “implementation-defined” part meant that we had very few WPT tests for that feature, really only those checking fetchpriority attributes for the DOM part.
Fortunately Mirko, who is a proponent of Test-driven development, had written quite a lot of internal WPT tests that use internal APIs to retrieve the internal priority.
To test Link headers, he used the handy wptserve pipes.
The only thing he missed was checking support in Early hints, but some WPT tests for early hints using WPT Python Handlers were available, so integrating them into Mirko’s tests was not too difficult.
It was also straightforward for Ziran and I to extend Mirko’s tests to cover fetch, img, and <link rel=preload as=image>, with one exception: when the fetch() method uses a non-default destination.
In most of these code paths, we call NS_NewChannel to perform a fetch.
But fetch() is tricky, because if the fetch event is intercepted, the event handler might call the fetch() method again using the same destination (e.g. image).
Handling this correctly involves multiple processes and IPC communication, which ended up not working well with the internal APIs used by Mirko’s tests.
It took me a while to understand what was happening in bug 1881040, and in the end I came up with a new approach.
Upstreamable WPT tests
First, let’s pause for a moment: all the tests we have so far use an internal API to verify the internal priority, but they don’t actually check how that internal priority is used by Firefox when it sends HTTP requests.
Valentin mentioned we should probably have some tests covering that, and not only would it solve the problem with fetch() calls in fetch event handlers, it would also remove the use of an internal API, making the tests potentially reusable by other browsers.
To make this kind of test possible, I added a WPT Python Handler that parses the urgency from a HTTP request and responds with an urgency-dependent resource, such as a stylesheet with different property values, an image of a different size, or an audio or video file of a different duration.
When a test uses resources with different fetch priorities, this influences the urgency values of their HTTP requests, which in turn influences the response in a way that the test can check for in JavaScript.
This is a bit complicated, but it works!
Conclusion
Fetch priority has been enabled in Firefox Nightly for a while, and experiments started recently to determine the optimal priority adjustments.
If everything goes well, we will be able to push this feature to the finish line after the (northern) summer.
Helping implement this feature also gave me the opportunity to work a bit on the Firefox networking code, which I had not touched since the collaboration with IPFS, and I learned a lot about resource loading and WPT features for HTTP requests.
To me, the “implementation-defined” part was still a bit awkward for the web platform.
We had to write our own internal WPT tests and do extra effort to prepare the feature for shipping.
But in the end, I believe things went relatively smoothly.

Hello Thunderbird Community! It’s August, where did our summer go? (or winter for the folks on the other hemisphere).
Our August has been packed with ESR fixes, team conferences, and some personal time off, so this is gonna be a bit of a shorter update, tackling more upcoming efforts than what recently landed on daily. Miss our last update? Find it here.
More Rust
If you’ve been looking at our monthly metrics you might have noticed that the % of Rust code in our code base is slowly increasing.
We’re planning to push forward this effort in the near future with more protocol reworks and clean up of low level code.
Stay tuned for more updates on this matter and some dedicated posts from the engineers that are driving this effort.
Pushing forward with Exchange
Nothing new to report here, other than that we’re continuing with this implementation and we hope to be able to enable this feature by default in a not so far off Beta.
The general objective before next ESR is to have complete email support and start tapping into Calendar and Address Book integration to offer the full experience out of the box.
Global database
This is also one of the most important pieces of work that we’ve been planning for a while. Bringing this to completion will drastically reduce our most common data loss problems as well as drastically speeding up the performance of Thunderbird when it comes to internal message search and archiving.
Calendar rebuild
Another very large initiative we’re kicking off during this new ESR cycle is a complete rebuild of our Calendar.
Not only are we going to clean up and improve our back-end code handling protocols and synchronization, but we’re also taking a hard look at our UI and UX, in order to provide a more flexible and intuitive experience, reducing the amount of dialogs, and implementing those features that users have come to expect from any calendaring application.
As usual, if you want to see things as they land you can always check the pushlog and try running daily, which would be immensely helpful for catching bugs early.
See ya next month.

On April 9th, 2024, the Rust Security Response WG disclosed CVE-2024-24576,
where std::process::Command incorrectly escaped arguments when invoking batch
files on Windows. We were notified that our fix for the vulnerability was
incomplete, and it was possible to bypass the fix when the batch file name had
trailing whitespace or periods (which are ignored and stripped by Windows).
The severity of the incomplete fix is low, due to the niche conditions
needed to trigger it. Note that calculating the CVSS score might assign a
higher severity to this, but that doesn't take into account what is required to
trigger the incomplete fix.
The incomplete fix is identified by CVE-2024-43402.
To determine whether to apply the cmd.exe escaping rules, the original fix
for the vulnerability checked whether the command name ended with .bat or
.cmd. At the time that seemed enough, as we refuse to invoke batch scripts
with no file extension.
If you are affected by this, and you are using Rust 1.77.2 or greater, you can
remove the trailing whitespace (ASCII 0x20) and trailing periods (ASCII 0x2E)
from the batch file name to bypass the incomplete fix and enable the
mitigations.
Rust 1.81.0, due to be released on September 5th 2024, will update the standard
library to apply the CVE-2024-24576 mitigations to all batch files
invocations, regardless of the trailing chars in the file name.
Affected versions
All Rust versions before 1.81.0 are affected, if your code or one of your
dependencies invoke a batch script on Windows with trailing whitespace or
trailing periods in the name, and pass untrusted arguments to it.

We want to thank Kainan Zhang (@4xpl0r3r) for responsibly disclosing this to us
according to the Rust security policy.
We also want to thank the members of the Rust project who helped us disclose
the incomplete fix: Chris Denton for developing the fix, Amanieu D'Antras for
reviewing the fix; Pietro Albini for writing this advisory; Pietro Albini,
Manish Goregaokar and Josh Stone for coordinating this disclosure.
We’ve all been there. You’re streaming music on Firefox and a great song plays but you have no idea what it’s called or who the artist is. If your phone is handy you could install a music recognition app, but that’s a clunky experience involving two devices. It would be a lot better to just click a button on Firefox and have the AudD® Music Recognition extension fetch you song details.
“And if you’re listening on headphones,” adds Mikhail Samin, CEO of AudD, “using a phone app is a nightmare. We tried to make learning what’s playing as uncomplicated as possible for users.” Furthermore, Samin claims browser based music recognition is more accurate than mobile apps because audio doesn’t get distorted by speakers or a microphone.
Of course, making things amazing and simple for users often requires complex engineering.
“It’s one thing for the browser to play audio from a source, such as an audio or video file on a webpage, to a destination connected to the device, like speakers,” explains Samin. “It’s another thing if a new and external part of the browser wants to add itself to the list of destinations. It isn’t straightforward to make an extension that successfully does that… Fortunately, we got some help from the awesome add-ons developer community. We went to the Matrix room.”
AudD is built to recognize any song from anywhere so long as it’s been properly published on digital streaming platforms. Samin says one of his team’s main motivations for developing AudD is simply the joy of connecting music fans with new artists, so install AudD to make sure you never miss another great musical discovery. If you’ve got any new ideas or feedback for the AudD team, they’re always eager to hear from users.

WebDriver is a remote control interface that enables introspection and control of user agents.As such itcanhelp developers to verify that their websites are working and performing well with all major browsers. The protocol is standardized by the W3C and consists of two separate specifications: WebDriver classic (HTTP) and the new WebDriver BiDi (Bi-Directional).
This newsletter gives an overview of the work we’ve done as part of the Firefox 130 release cycle.
Contributions
Firefox – including our WebDriver implementation – is developed as an open source project, and everyone is welcome to contribute. If you ever wanted to contribute to an open source project used by millions of users, or are interested in some experience in software development, jump in.
We are always grateful to receive external contributions, here are the ones which made it in Firefox 130:
Congratulations to 404 Media, which celebrated its successful first year on August 22. They link to other next-generation news sites, owned by the people who write for them. I checked for ads.txt files and advertiser pages to see which are participating in the conventional RTB ad system and which are doing something else. (404 Media does have an ads.txt file managed by BuySellAds.)
Hell Gate: New York City news (not just for those who finally canceled their subscriptions to that other New York site) (ads.txt not found, advertise with Hell Gate is just a page with a contact email address.)
Remap: Video game site that also covers a variety of topics, including but not limited to games, rooting for sports teams that break your heart, inflatable hot tubs, hanging out on car auction websites, and more.Old News from the Latest Disasters: [T]he fact that these studio tell-all features have started to feel so same-y says less about the journalist reporting them and more about how mundane this kind of dysfunction is in AAA game development. (ads.txt not found, no ad contact or page)
Another good example, not on 404 Media’s list, is The Kyiv Independent — News from Ukraine, Eastern Europe. The Kyiv Independent was born out of a fight for freedom of speech. It was co-founded by a group of journalists who were fired from the Kyiv Post, then a prominent newspaper, as the owner attempted to take the newsroom under control and end its critical coverage of Ukrainian authorities. Instead of giving up, the fired team founded a new media outlet to carry on the torch — and be a truly independent voice of Ukraine.Opinion: AI complacency is compromising Western defense (ads.txt found, looks like they use an ad management service.)
What all these sites have in common is a focus on subscriber/member revenue and first-party data.
As a privacy nerd, I’m an optimist about this apparent mess. Yes, part of success in running a modern news operation is figuring out how to get by without legacy management layers and investors (404 Media Shows Online Journalism Can Be Profitable When You Remove Overpaid, Fail-Upward Brunchlords From The Equation). But the other big set of trends is technical and regulatory improvements that—if kept up and not worked around—will lower the ROAS (return on ad spendnot rodents of average size) for surveillance advertising. So the Internet optimist version of the story is
Big Tech value extraction drives independent journalists to business models other than surveillance advertising
With the money saved in step 3, people can afford more subscriptions.
The big objection to that is: what about free riding problems? Won’t people choose not to subscribe, or choose infringing or AI-exfiltrated versions of content? But most people aren’t as likely to try to free ride as tech executives are. The rise of 404 Media and related sites is a good sign. More:Sunday Internet optimism
Satori Threat Intelligence Alert: Camu cashes out ads on piracy content (This is why you don’t build an inclusion list by looking at the ad reports and adding what looks legit. Illegal sites can check Referer headers and hide their real content from advertisers who cut and paste the URL. Referer lists have to be built from known legit sources like customer surveys, press lists, support tickets, and employee chat logs.)
Your use of AI is directly harming the environment I live inInstead of putting limits to “AI” and cryptocoin mining, the official plan is currently to destroy big parts of places like Þjórsárdalur valley, one of the most green and vibrant ecosystems in Iceland. That’s why I take it personally when people use “AI” models and cryptocoins. You are complicit in creating the demand that is directly threatening to destroy the environment I live in. None of this would be happening if there wasn’t demand so I absolutely do think the people using these tools and services are personally to blame, at least partially, for the harm done in their name.
Thinking About an Old Copyright Case and Generative AIThe precedent in Wheaton has often been highlighted by anti-copyright scholars because it limits the notion that copyright rights are in any sense natural rights. This, in turn, supports the skeptical (I would say cynical) view that copyright is a devil’s bargain with authors, begrudgingly granting a temporary “monopoly” in exchange for production and distribution of their works. But aside from the fact that the Court of 1834 stated that the longstanding question remained “by no means free from doubt,” its textual interpretation of the word securing was simply unfounded. (Some good points here. IMHO neither the copyright maximalists nor the techbro my business model is always fair use crowd are right. Authors and artists have both natural rights and property-like commercial interests that are given to them by the government as a subsidy.)
Plain Vanilla – a tutorial website for vanilla web developmentThe plain vanilla style of web development makes a different choice, trading off a few short term comforts for long term benefits like simplicity and being effectively zero-maintenance. This approach is made possible by today’s browser landscape, which offers excellent web standards support.
WebXR (@msub2, #33245) and flexbox (@mrobinson, #33186) are now enabled by default, and web APIs that return promises now correctly reject the promise on failure, rather than throwing an exception (@sagudev, #32923, #32950).
‘position: relative’ is now supported on flex items (@mrobinson, #33151), ‘z-index’ always creates stacking contexts for flex items (@mrobinson, #32961), and we now give flex items and flex containers their correct intrinsic sizes (@delan, @mrobinson, @mukilan, #32854).
We’re now working on support for bidirectional text, with architectural changes to the fragment tree (@mrobinson, #33030) and ‘writing-mode’ interfaces (@mrobinson, @atbrakhi, #33082), and now partial support for the ‘unicode-bidi’ property and the dir attribute (@mrobinson, @atbrakhi, #33148).
Note that the dir=auto value is not yet supported.
<figcaption>servoshell now has a more elegant toolbar, tabbed browsing, and a clean but useful “new tab” page.</figcaption>
Servo now runs better on Windows, with keyboard navigation now fixed (@crbrz, #33252), --output to PNG also fixed (@crbrz, #32914), and fixes for some font- and GPU-related bugs (@crbrz, #33045, #33177), which were causing misaligned glyphs with incorrect colors on servo.org (#32459) and duckduckgo.com (#33094), and corrupted images on wikipedia.org (#33170).
Our devtools support is becoming very capable after @eerii’s final month of work on their internship project, with Servo now supporting the HTML tree (@eerii, #32655, #32884, #32888) and the Styles and Computed panels (@eerii, #33025).
Stay tuned for a more in-depth post about the Servo devtools!
Changes for Servo developers
Running servoshell immediately after building it is now several seconds faster on macOS (@mrobinson, #32928).
We now run clippy in CI (@sagudev, #33150), together with the existing tidy checks in a dedicated linting job.
Servo now has new CI runners for Windows builds (@delan, #33081), thanks to your donations, cutting Windows-only build times by 70%!
We’re not stopping at Windows though, and with new runners for Linux builds just around the corner, your WPT try builds will soon be a lot faster.
We’ve been running some triage meetings to investigate GitHub issues and coordinate our work on them.
The next Servo issue triage meeting is on 2 September at 10:00 UTC.

Engine reliability
August has been a huge month for squashing crash bugs in Servo, including on real-world websites.
We’ve fixed crashes when rendering floats near tables in the HTML spec (@Wuelle, #33098), removed unnecessary explicit reflows that were causing crashes on w3schools.com (@jdm, #33067), and made the HTML parser re-entrant (@jdm, #32820, #33056, html5ever#548), fixing crashes on kilonova.ro (#32454), tweakers.net (#32744), and many other sites.
Several other crashes have also been fixed:
crashes when resizing windows with WebGL on macOS (@jdm, #33124)
crashes when rendering text with extremely long grapheme clusters (@crbrz, #33074)
crashes when rendering text with tabs in certain fonts (@mrobinson, #32979)
crashes in the parser after calling window.stop() (@Taym95, #33173)
crashes when passing some values to console.log() (@jdm, #33085)
crashes when parsing some <img srcset> values (@NotnaKO, #32980)
crashes when parsing some HTTP header values (@ToBinio, #32973)
crashes when setting window.opener in certain situations (@Taym95, #33002, #33122)
crashes when calling new AudioContext() with unsupported options (@Taym95, #33023)
intermittent crashes in WRSceneBuilder when exiting Servo (@Taym95, #32897)
We’ve fixed a bunch of BorrowError crashes under SpiderMonkey GC (@jdm, #33133, #24115, #32646), and we’re now working towards preventing this class of bugs with static analysis (@jdm, #33144).

AI Has Created a Battle Over Web CrawlingThe report, Consent in Crisis: The Rapid Decline of the AI Data Commons, notes that a significant number of organizations that feel threatened by generative AI are taking measures to wall off their data. (IMHO this is not just a TOS or copyright issue. In the medium term the main problem for AI scrapers is going to be privacy and defamation law. Meta AI Keeps Telling Strangers It Owns My Phone Number - Business Insider)
Opt Out of Clearview AI GiveawayClass actions are terminally disappointing, but this one is especially egregious and it is worthy of special attention. We think you should opt out. Not just as a protest, but to preserve your rights in the event of further litigation. Here is how to do it. The deadline is September 20th.
Point of order: I decided not to put some otherwise good links in here because the writers chose to stick a big obvious AI-generated image on them. That’s like Rolling Coal for the web. Unless your intent is to claim membership in evil oligarch fan club or artist hater club, cut it out. I can teach you to find perfectly good Creative Commons images if you don’t have an illustration budget.
We’re excited to share a new project we’ve been working on at Thunderbird called Appointment. Appointment makes it simple to schedule meetings with anyone, from friends and family to colleagues and strangers. Escape the endless email threads trying to find a suitable meeting time across multiple time zones and organizations.
With Appointment, you can easily share your customized availability and let others schedule time on your calendar. It’s simple and straightforward, without any clutter.
If you have tried similar tools, Appointment will feel familiar, while capturing what’s unique about Thunderbird: it’s open source and built on our fundamental values of privacy, openness, and transparency. In the future, we intend for Appointment to be part of a wider suite of helpful products enhancing the core Thunderbird experience. Our ambition is to provide you with not only a first-rate email application but a hub of productivity tools to make your days more efficient and stress-free.
We’ll be rolling out Appointment in phases, continuing to improve it as we open up access to more people. It’s currently in closed beta, so we encourage you to sign up for our waiting list. Let us know what features you find valuable and any improvements you’d like to see. Your feedback will be invaluable as we make this tool as useful and seamless as possible.
To that end, the development repository for Appointment is publicly available on Github, and we encourage any future testers or contributors to get involved and build this with us.
Free yourself from cluttered scheduling apps and never-ending email threads. The simplicity of Appointment lets you find that perfect meeting time, without wasting your precious time.
When I began my 16-month journey as a Software Engineer intern at Mozilla, I had no idea how enriching the experience would be. I had just finished my third-year as a computer science student at the University of Toronto, passionate about Artificial Intelligence (AI), Machine Learning (ML), and software engineering, with a thirst for hands-on experience. Mozilla, with its commitment to the open web and global community, was the perfect place for me to grow, learn, and contribute meaningfully.
Starting off strong on day one at Mozilla—calling the shots from the big screen :)!
Integrating into a Global Team
Joining Mozilla felt like being welcomed into a global family. Mozilla’s worldwide presence meant that asynchronous communication was not just a convenience but a necessity. My team was scattered across various time zones around the world—from Berlin to Helsinki, Slovenia to Seattle, and everywhere in between. Meanwhile, I was located in Toronto, where morning standups became my lifeline. The early hours of the day were crucial; I had to ensure all my questions were answered before my teammates signed off for the day. Collaborating across continents with a diverse team honed my adaptability and proficiency in asynchronous communication, ensuring smooth project progress despite time zone differences. This taught me the art of clear, concise communication and the importance of being proactive in a globally distributed team.
Our weekly team meeting, connecting from all corners of the globe!
Working on localization with such a diverse team gave me a unique perspective. I learned that while we all used the same technology, the challenges and solutions were as diverse as the locales we supported. This experience underscored the importance of creating technology that is not just globally accessible but also locally relevant.
Who knew software engineering could be so… circus-y? Meeting the team in style at Mozilla’s All Hands event in Montréal!
Building Success Through Teamwork
During my internship, I was treated as a full-fledged engineer, entrusted with significant responsibilities that allowed me to lead projects. This experience honed my strategic thinking and built my confidence, but it also taught me the importance of collaboration. Working closely with a team of three engineers, I quickly learned that effective communication was essential to our success. I actively participated in code reviews, feature assessments, and bug resolutions, always keeping my team informed through regular updates in standups and Slack. This open communication not only fostered strong relationships but also made me an effective team player, ensuring that our collective efforts were aligned and that we could achieve our goals together.
Driving Innovation
One of the things I quickly realized at Mozilla was that innovation isn’t just about coming up with new ideas—it’s about identifying areas for improvement and enhancing them. My interest in AI led me to spot an opportunity to elevate the translation process in Pontoon, Mozilla’s localization platform. After thorough research and discussions with my mentor and team, I proposed integrating large language models to boost the platform’s capabilities. This proactive approach not only enhanced the platform but also showcased my ability to think critically and solve problems effectively.
Diving into the Tech Stack
Mozilla gave me the opportunity to dive deep into a tech stack that was both challenging and exciting. I worked extensively with Python using the Django framework, React, TypeScript, and JavaScript, along with HTML and CSS. But it wasn’t just about the tools—it was about applying them in ways that would have a lasting impact.
One of my most significant projects was leading the integration of GPT-4 into Pontoon. This wasn’t just about adding another tool to the platform; it was about enhancing the translation process in a way that captured the subtle nuances of language, something that traditional machine translation tools often missed. The result? A feature that allowed localizers to rephrase text, or make text more formal or informal as needed, ultimately ensuring that Mozilla’s products resonated with users worldwide.
This project was a full-stack adventure. From prompt engineering on the backend to crafting a seamless frontend interface, I was involved in every stage of the development process. The impact was immediate and widespread—by August 2024, the feature had been used over 2,000 times across 52 distinct locales. Seeing something I worked on make such a tangible difference was incredibly rewarding. You can read more about this feature in my blog post here.
Another project that stands out is the implementation of a light theme in Pontoon, aimed at promoting accessibility and enhancing user experience. Recognizing that a single dark theme could be straining for some users, I spearheaded the development of a light theme and system theme option that adhered to accessibility standards and catered to diverse user preferences. Within the first six months of its launch, the feature was adopted by over 14% of users who logged in within the last 12 months, significantly improving usability and demonstrating Mozilla’s commitment to inclusive design.
Building a Stronger Community
Mozilla’s commitment to community is one of the things that drew me to the organization, and I was thrilled to contribute to it in meaningful ways. One of my proudest achievements was initiating the introduction of gamification elements in Pontoon. The goal was to enhance community engagement by recognizing and rewarding contributions through badges. By analyzing user data and drawing inspiration from platforms like Duolingo and GitHub, I helped design a system that not only motivated contributors but also enhanced the trustworthiness of translations.
But my impact extended beyond that. I had the opportunity to interact with our global audience and participate in various virtual events focused on engaging with our localization community. For instance, I took part in the “Three Women in Localization” interview, where I shared my experiences as a female engineer in the tech industry. I also participated in a fireside chat with the localization tech team to discuss our work and the future of localization at Mozilla. More recently, I organized a live virtual interview featuring the Firefox Translations team, which turned out to be our most engaging online event to date. It was an incredible opportunity to connect with Mozilla’s global community, discuss important topics like privacy and AI, and facilitate real-time interaction. These experiences not only allowed me to share my insights but also deepened my understanding of the broader community that powers Mozilla’s mission.

From Mentee to Mentor
During the last four months of my internship, I had the opportunity to mentor and onboard our new intern, Harmit Goswami, who would be taking over my role once I returned to my last semester of university. My team entrusted me with this responsibility, and I guided him through the onboarding process—helping him get everything set up, introducing him to the codebase, and supporting him as he tackled his first bugs.
Mentoring our new intern, Harmit, as he joins our weekly tech team call for the first time from the Toronto office—welcoming him to the Mozilla family, one Zoom call at a time!
This experience taught me the importance of clear communication, setting expectations, and creating a learning path for his growth and success. I was fortunate to have an amazing mentor, Matjaž Horvat, throughout my internship, and it was incredibly rewarding to take what I had learned from him and pass it on. In the process, I also gained a deeper understanding of my own skills and how to teach and guide others effectively.
Learning and Growing Every Day
The fast-paced, collaborative environment at Mozilla pushed me to learn new technologies and skills on a tight schedule. Whether it was diving into Django for backend development or mastering the intricacies of version control with Git and GitHub, I was constantly learning and growing. More importantly, I learned the value of adaptability and how to thrive in an open-source work culture that was vastly different from my previous experiences in the financial sector.
Reflecting on the Journey
As I wrap up my internship, I can’t help but reflect on how much I’ve grown—both as an engineer and as a person.
As a person, I was able to step out of my comfort zone and host virtual events that were open to both the company and the public, enhancing my confidence and public speaking skills. Engaging with a diverse audience and facilitating meaningful discussions taught me the importance of effective communication and community engagement.
As an engineer, I had the opportunity to lead my own projects from the initial idea to deployment, which allowed me to fully immerse myself in the software development lifecycle and project management. This experience sharpened my technical acumen and taught me how to provide constructive feedback during senior code reviews, ensuring code quality and adherence to best practices. Beyond technical development, I expanded my expertise by adopting a user-centric approach—writing proposal documents, conducting research, analyzing user data, and drafting detailed specification documents. This comprehensive approach required me to blend technical skills with strategic thinking and user-focused design, ultimately refining my problem-solving, research, and communication abilities. These experiences made me a more versatile and well-rounded engineer.
This journey has been about more than just writing code. It’s been about building something that matters, connecting with a global community, and growing into the kind of engineer who not only solves problems but also embraces challenges with creativity and resilience. As I look ahead to the future, I’m excited to continue this journey, armed with the knowledge, skills, and passion that Mozilla has helped me cultivate.
Acknowledgments
I want to extend my deepest gratitude to my manager, Francesco Lodolo, and my mentor, Matjaž Horvat, for their unwavering support and guidance throughout my internship. To my incredible team and the entire Mozilla community, thank you for fostering an environment of learning, collaboration, and innovation. This experience has been invaluable, and I will carry these lessons and memories with me throughout my career.
*Thank you for reading about my journey! If you have any questions or would like to discuss my experiences further, feel free to reach out via Linkedin.
Special shout-out to Daniele (egglessness) who landed a new experimental Picture-in-Picture feature that can be enabled in Firefox 130! This feature automatically triggers Picture-in-Picture mode for any playing video when the associated tab is backgrounded. This can be enabled in about:settings#experimental
Olli Pettay fixed very long cycle collection times in workers which improved performance when Debugging large files in the DevTools Debugger (#1907794)
Want to highlight sample code from your favorite dev site? Now it’s possible with the latest Nightly version.
Mandy has added support for showing search restriction keywords when users type @ in the address bar. If you want to check it out, be sure to set browser.urlbar.searchRestrictKeywords.featureGate to true.
Fixed origin control messages for MV3 extensions requesting access to all urls through two separate host permissions (e.g. “http://*/*” and “https://*/*”, instead of a single “<all_urls>” host permission) – Bug 1856383
WebExtension APIs
Fixed webRequest.getSecurityInfo to make sure the options parameter is optional – Bug 1909474
Thanks to Cauã Sene (cauasene00) for updating our tests to fully avoid requests related to system add-on updates. Previously they would just be redirected to a dummy URL and as a result were polluting our test logs. (#1904310)
Updates:
Sasha implemented a new event called browsingContext.navigationFailed, which is raised whenever a navigation fails (e.g. canceled, network error, etc.). In combination with other events such as browsingContext.load, this allows clients to monitor navigations from start to finish in all scenarios (#1846601)
Sasha fixed a bug in the browsingContext.navigate command. If the client used the parameter wait=none, we now resolve the command even if the navigation triggered a “beforeunload” prompt. (#1763134)
Sasha fixed a bug with the network.authRequired event, which was previously duplicated after each manual authentication attempt, leading to too many events. (#1899711)
Julian updated the data-channel-opened notification to also be emitted for data URL channels created in content processes. Thanks to this WebDriver BiDi will now raise network events for all data URL requests. (#1904343)
Julian updated the logic for the network.responseCompleted and network.fetchError events in order to raise them at the right time, and ensure a correct ordering of events. For instance, per spec for a successful navigation network.responseCompleted should be raised before browsingContext.load. (#1882803)
Migration Improvements
We’re working with UX and PM on a wizard that will walk users through getting backup enabled and configured just how they like it. We’re still in the midst of breaking that down, but the metabug is here.
fchasen has a patch up that, after recovery, will make the recovered profile the default, and shutdown the browser that initiated recovery
kpatenio landed the password rules tooltip to the backup management UI, and is working on efficiently checking user passwords against a local copy of the same “common password” list that FxA uses.
Picture-in-Picture
Some strings were updated to use capitalised “Picture-in-Picture” rather than “picture-in-picture” per our word list (bug)
Mortiz has created a new test function, SearchTestUtils.setRemoteSettingsConfig for setting the search configuration in xpcshell-tests, and improved SearchTestUtils.updateRemoteSettingsConfig.
Both will take a partial search configuration & expand it into a full configuration. This simplifies test-setup, so that you only need to specify the bits that are important to the test.
Some tests are already using these, we’ll be rolling it out to more soon.
One of the responsibilities of the leadership council,
formed by RFC 3392, is to solicit feedback on a yearly basis from the Project
on how we are performing our duties.
Each year, the Council must solicit feedback on whether the Council is
serving its purpose effectively from all willing and able Project members and
openly discuss this feedback in a forum that allows and encourages active
participation from all Project members. To do so, the Council and other
Project members consult the high-level duties, expectations, and constraints
listed in this RFC and any subsequent revisions thereof to determine if the
Council is meeting its duties and obligations.
This is the council's first year, so we are still figuring out the best way to
do this. For this year, a short survey was sent out to all@ on June 24th, 2024,
ran for two weeks, and we are now presenting aggregated results from the
survey. Raw responses will not be shared beyond the leadership council, but the
results below reflect sentiments shared in response to each question. We invite
feedback and suggestions on actions to take on Zulip or through direct
communication to council members.
We want to thank everyone for their feedback! It has been very valuable to hear
what people are thinking. As always, if you have thoughts or concerns, please
reach out to your council representative any time.
Survey results
We received 53 responses to the survey, representing roughly a 32% response
rate (out of 163 current recipients of all@).

Areas that are going well
For the rest of the questions we group responses into rough categories. The
number of those responses is also provided; note that some responses may have
fallen into more than one of these categories.
(5) Less drama
(5) More public operations
(5) Lack of clarity / knowledge about what it does
It's not obvious why this is a "going well" from the responses, but it was
given in response to this question.
(4) General/inspecific positivity.
(2) Improved Foundation/project relations
(2) Funding travel/get-togethers of team members
(1) Clear representation of members of the Project
(1) Turnover while retaining members
Areas that are not going well
(15) Knowing what the council is doing
(3) Not enough delegation of decisions
(2) Finding people interested in being on the council / helping the council
(1) What is the role of the project directors? Are they redundant given the council?
(2) Too conservative in trying things / decisions/progress is made too slowly.
(1) Worry over Foundation not trusting Project
Suggestions for things to do in the responses:
(2) Addressing burnout
(2) More social time between teams
(2) More communication/accountability with/for the Foundation
(2) Hiring people, particularly for non-technical roles
(1) Helping expand the moderation team
(1) Resolving the launching pad issues, e.g., through "Rust Society" work
(1) Product management for language/compiler/libraries
Takeaways for future surveys
We should structure the survey to specifically ask about high-level duties
and/or enumerate areas of interest (e.g., numeric responses on key questions
like openness and effectiveness)
Consider linking published material/writing 1-year retrospective and that
being linked from the survey as pre-reading.
We should disambiguate between neutral and "not enough information/knowledge
to answer" responses in multiple choice response answers.
Proposed action items
We don't have any concrete proposed actions at this time, though are interested
in finding ways to have more visilibity for council activities, as that seems
to be one of the key problems called out across all of the questions asked. How
exactly to achieve this remains unclear though.
As mentioned earlier, we welcome input from the community on suggestions for
both improving this process and for actions to change how the council operates.
Really good example of a market failure in software quality incentivization: ansuz / ऐरन: “there’s a wee story brewing in…” Read the whole thing. Good counterexample for money talks. With the wrong market design, money says little or nothing.
To summarize (you did read the whole thing, right?) in 2019, a software algorithm called a Variable Delay Function (VDF) was the subject of a $100,000 reward program. Daniel J. Bernstein asked, in a talk recorded on video if the VDF was vulnerable to a method that he had already published in a paper.
If Bernstein was right, then a developer who
read Bernstein’s paper on the subject
applied Bernstein’s work to attacking the VDF
and was first to claim the reward
could earn $100,000. But the money was left unclaimed—nobody got the bounty, and the attack on VDFs didn’t come out until now.
It would take some time to read and understand the paper, and to figure out if it really described a way to break the VDF—but that’s not the main problem. The catch with the bounty scheme is that as a contender for the bounty, you don’t know how many other contenders there are and how fast they work. If 64 people (the number of viewers on the video) are working on it, and Bernstein is 95% likely to be right about the paper, then the expected payout is $100,000 × 0.95 × 1/64 = $1,484.38.
In this case, the main purpose of the bounty was to collect information about the quality of the VDF algorithm, and it failed to achieve this purpose. A better way to achieve this information-gathering goal is to use a system that also incentivizes meta-work such as evaluating whether a particular approach is relevant to a particular problem.

Hinweis: Dies ist eine deutsche Übersetzung des englischen Original-Blogbeitrags. Der ursprüngliche Beitrag dient weiterhin als die ursprüngliche und maßgebliche Erklärung des Themas.
Im Internet hat sich ein dichtes Netz zur Überwachung entwickelt, wo Werbetreibende und Werbeplattformen detaillierte Informationen über die Online-Aktivitäten der Nutzenden sammeln. Bei Mozilla glauben wir, dass diese Informationen ausschließlich den einzelnen Personen gehören und dass ihre uneingeschränkte Sammlung eine nicht hinnehmbare Verletzung des Datenschutzes ist. Wir haben in Firefox immer fortschrittliche Anti-Tracking-Technologien bereitgestellt und werden dies auch weiter tun. Allerdings glauben wir, dass sich im Ökosystem auch weiterhin neuartige Techniken zur User-Nachverfolgung entwickeln werden, solange es einen starken wirtschaftlichen Anreiz dazu gibt.
Wir sind darüber hinaus sehr besorgt über Bestrebungen in einigen Ländern, Anti-Tracking-Funktionen in Browsern einzuschränken. In einer Welt, in der die Gesetzgebung gegensätzliche Interessen unter einen Hut bringen muss, ist es gefährlich, wenn sich Werbung und Datenschutz in einem Nullsummen-Konflikt befinden.
Um diese technischen und regulatorischen Gefahren für den User-Datenschutz anzugehen und gleichzeitig Mozillas Mission voranzubringen, entwickeln wir eine neue Technologie namens Privacy Preserving Attribution (PPA, im Deutschen: datenschutzfreundliche Werbemessung). Mit dieser Technologie soll ein Weg für die Werbetreibenden aufgezeigt werden, die Werbewirksamkeit insgesamt zu messen, ohne Informationen über bestimmte Einzelpersonen zu sammeln.
Die Funktionsweise der PPA
Anstatt private Informationen zu sammeln, um zu bestimmen, wann bestimmte User mit einer Werbung interagieren, basiert PPA auf neuartigen kryptographischen Techniken, die darauf ausgelegt sind, die Daten der User zu schützen und gleichzeitig aggregierte Attribution zuzulassen. So können Werbetreibende aggregierte Statistiken bekommen, um zu prüfen, ob ihre Werbung funktioniert. Dabei wird jedoch keinerlei zielgerichtete Werbung (Ad Targeting) ermöglicht. Im Kern wird bei PPA ein System zur Mehrparteien-Berechnung (Multi Party Computation, MPC) namens Distributed Aggregation Protocol (DAP) genutzt, das in Partnerschaft mit dem Divvi-Up-Projekt der Internet Security Research Group (ISRG), der Organisation hinter Let‘s Encrypt, verwendet wird.
Und so funktioniert es:
Anstatt individuelle Surfaktivitäten offenzulegen, um zu bestimmen, wer eine bestimmte Werbung ansieht, nutzt PPA mathematische Verfahren, mit denen die Konsumentendaten privat bleiben. Interagieren User mit einem Werbe-Banner oder einem Werbetreibenden, so wird die jeweilige Interaktion auf deren Geräten in zwei unkenntlich gemachte Teile aufgeteilt – jedes dieser Segmente ist verschlüsselt und wird dann an zwei unabhängig voneinander arbeitende Dienste gesendet. Ähnliche Segmente von vielen Usern werden dann von diesen Diensten zusammengeführt um eine aggregierte Zahl zu generieren. Diese Zahl gibt an, wie viele Menschen eine Aktion (etwa das Anmelden zu einem Newsletter) durchgeführt haben, nachdem sie eine Werbung gesehen haben – all dies jedoch ohne Informationen über die Aktivitäten irgendeiner Einzelperson gegenüber dem Dienst oder dem Werbetreibenden offenzulegen. Im Einzelnen werden die folgenden Schritte durchgeführt:
Verschlüsselung der Daten: Interagiert ein User mit einer Werbung oder einem Werbetreibenden, so wird im Browser ein Ereignis in Form eines Wertes protokolliert. Dieser Wert wird in einzelne, unkenntlich gemachte Segmente geteilt und dann verschlüsselt. Jedes Segment wird an eine jeweils andere Stelle adressiert – eins an Divvi Up und eins an Mozilla – auf diese Weise hat keine Stelle für sich jemals beide Segmente.
Maskierung: Als zusätzlicher Schutz werden die Segmente an Divvi Up und Mozilla über ein Oblivious HTTP-Relay übermittelt, das von einem Drittanbieter (Fastly) betrieben wird. So wird sichergestellt, dass weder Divvi Up noch Mozilla auch nur die IP-Adresse des unkenntlich gemachten Segments kennen, das sie erhalten. Der Traffic ist für Fastly nicht einsehbar und mit anderen Anfragearten gemischt, sodass auch sie keine Informationen daraus ziehen können.
Aggregation: Divvi Up und Mozilla führen jeweils bei sich alle unkenntlich gemachten Segmente zusammen, die sie erhalten, um einen (ebenfalls unkenntlich gemachten) Aggregationswert zu bilden. Das heißt, dass die Daten vieler User zusammengeführt werden, ohne dass irgendjemand der Beteiligten die Inhalte oder Quellen der jeweiligen individuellen Datenpunkte erfährt.
Randomisierung: Darüber hinaus wird jede Hälfte vor der Weitergabe noch mit zufälligem Rauschen versehen, um Differential Privacy (differentielle Privatsphäre) zu gewährleisten, was mathematisch sicherstellt, dass aus Trends in den aggregierten Daten nicht auf individuelle Aktivitäten geschlossen werden kann.
Zusammenführung: Divvi Up und Mozilla senden dann ihre unkenntlich gemachten Werte im Ganzen an den Werbetreibenden, sodass daraus zusammengeführte informative Kenngrößen gebildet werden können. Dies sind aggregierte Kenngrößen zu allen Usern, die keinerlei Informationen zu Einzelpersonen offenbaren.
Durch die Verwendung fortschrittlicher Verschlüsselungsmethoden stellt PPA sicher, dass die Userdaten während des gesamten Werbemessungsprozesses privat und sicher bleiben. An keinem Punkt hat eine einzelne Partei Zugang zur individuellen Surfaktivität von bestimmten Usern – eine tiefgreifende Verbesserung im Vergleich zum derzeitigen Modell.
Zu erfüllende Vorgaben
Ein entscheidender Gesichtspunkt bei der Entwicklung der PPA war die Beachtung der Rechtsvorschriften zum Datenschutz, wie etwa der Datenschutz-Grundverordnung (DSGVO). Im Folgenden sind einige Gründe aufgeführt, warum wir glauben, dass die PPA den strengen Anforderungen dieser Rechtsvorschriften entspricht.
Anonymisierung: Die von PPA genutzte Verbindung von IP-Schutz, Aggregation und differentieller Privatsphäre bricht die Verbindung zwischen einem Messungsereignis und einer bestimmten Einzelperson. Wir sind der Ansicht, dass dies die hohen Anforderungen der DSGVO zur Anonymisierung erfüllt.
Datensparsamkeit: Für die vom Browser übermittelten Informationen gelten strenge Praktiken zur Datensparsamkeit. Die einzige in Berichten enthaltene Information ist ein einzelnes, begrenztes Histogramm.
Unsichtbare Deaktivierung: Wenn PPA inaktiv ist, lässt es Attributionsberichte von Websites zu und verwirft sie unbemerkt. Das bedeutet, dass diese Websites nicht erkennen können, ob jemand PPA aktiviert hat oder nicht. Mit dieser Maßnahme wird eine Ungleichbehandlung oder Identifizierung (Fingerprinting) durch Websites aufgrund der Verfügbarkeit der Funktion verhindert.
Prototyp-Implementierung und User-Tests
Die aktuelle Implementierung von PPA in Firefox ist ein Prototyp, der das Konzept validieren und die aktuellen Arbeiten an Standards beim World Wide Web Consortium (W3C) unterstützen soll. Diese begrenzte Implementierung ist erforderlich, um das System unter Realbedingungen zu testen und wertvolles Feedback zu erhalten.
Der Prototyp ist mit einem aktivierten Origin Trial versehen – so wird verhindert, dass das API in irgendeiner Weise irgendeiner Website gegenüber sichtbar ist, sofern dies nicht explizit von Mozilla erlaubt wurde. Im ersten Test sind ausschließlich von Mozilla betriebene Sites enthalten– genauer, Werbung für Mozilla VPN, die im Mozilla Developer Network (MDN) angezeigt wird. Wir haben diesen Ansatz gewählt, um genügend Teilnahme zur Bewertung der Systemleistung und des Datenschutzes zu gewährleisten und gleichzeitig sicherzustellen, dass er unter streng kontrollierten Bedingungen getestet wird.
Nächste Schritte und Pläne für die Zukunft
Besucht ein User in relevanten Märkten während der Testphase die MDN-Website mit Firefox und sieht eine Werbung für Mozilla VPN, die Teil dieses Tests ist, so werden im Hintergrund alle im vorigen Abschnitt beschriebenen technischen Schritte durchgeführt, damit wir die Technik testen können. Weder verlassen dabei Daten zu individuellen Surfaktivitäten das Gerät, noch werden diese eindeutig identifizierbar. Wie immer haben die User die Möglichkeit, diese Funktion in ihren Firefox-Einstellungen abzuschalten.
Im weiteren Verlauf wird unser unmittelbarer Fokus darauf liegen, die PPA anhand der Rückmeldungen aus diesem ersten Prototyp zu verfeinern und zu verbessern. Dies werden die Themen der nächsten Monate sein:
Ausweitung der Tests: Abhängig von den ersten Ergebnissen fügen wir möglicherweise weitere Websites in der Testphase ein und überwachen sorgsam die Ergebnisse, um sicherzustellen, dass das System wie gewollt arbeitet. Wegen der laufenden Standard-Entwicklung nutzt der Prototyp ein nicht standardkonformes API und wird daher nie in seiner derzeitigen Form im Netz insgesamt zu sehen sein.
Transparenz und Kommunikation: Wir stehen für Transparenz hinsichtlich der Funktionsweise der PPA und des Schutzes der Nutzerdaten. Wir werden weiterhin Updates veröffentlichen und die Community in Bezug auf etwaige Bedenken einbeziehen.
Zusammenarbeit und Entwicklung von Standards: Mozilla wird weiterhin mit anderen Unternehmen und öffentlichen Normungsstellen daran arbeiten, Technologien zu entwickeln und zu standardisieren, die die Privatsphäre achten. Unser Ziel ist eine robuste, branchenweite Lösung, die allen Nutzern zugutekommt.
Schließlich ist es unsere Vision, privatsphärenfreundliche Technologien wie PPA mit dem Ziel zu entwickeln, zu validieren und bereitzustellen, am Ende invasive Trackingpraktiken überflüssig zu machen. Indem wir deren Machbarkeit nachweisen, wollen wir eine Online-Umgebung mit mehr Sicherheit und Privatsphäre für alle schaffen. Eine Organisation alleine kann diese Herausforderungen nicht meistern. Uns ist dabei Feedback wichtig, und wir hoffen, dass unsere Anstrengungen weitere Organisationen veranlassen, in ähnlicher Weise innovativ tätig zu werden. Vielen Danke für Ihre Unterstützung auf dieser Reise. Gemeinsam können wir ein besseres Internet schaffen, in dem die Privatsphäre gestärkt wird.
Not all heroes wear capes. Some of our favorite superheroes are the community members who provide Thunderbird support on the Mozilla Support (SUMO) forums. The community members who help others get to the root of their problems are everyday heroes, and this video shows what it takes to become one of them. Spoiler – you don’t need a spider bite or a tragic origin story! All it takes is patience, curiosity, and a little work.
In our next Office Hours, we’ll be chatting with our Thunderbird Council! One week before we record, we’ll put out a call for questions on socialmedia and on the relevant TopicBox mailing lists. And if you have an idea for an Office Hours you’d like to see, let us know in the comments or email us at officehours@thunderbird.net.
Office Hours: Thunderbird Support (Part 2)
In the sleeper sequel hit of the summer, we sat down to chat with Wayne Mery, who in addition to his work with releases, is our Community Manager as well. Like Roland, Wayne has been with the project practically from the start, and was one of the first MZLA employees. If you’ve spent any time on SUMO, our subreddit, or Bugzilla, chances are you’ve seen Wayne in action helping users.
In this chat and demo, Wayne walks us through the steps to becoming a support superhero. The SUMO forums are community-driven, and (every additional contributor means more knowledge and hopefully fewer unanswered questions.) (This would be a good sport for something about the power of community in open source, and how many of us who got into open source as a career started as volunteers in forums like these.)
The video includes:
The structure and markup language of the SUMO Forums
How to find questions that need answering
Where to meet and chat with other volunteers online
A demonstration of the forum’s workflow
A very helpful DOs and DON’Ts guide
A demo where Wayne answers new questions to show his advice in action
Watch, Read, and Get Involved
This chat helps demystify how we and the global community provide support for Thunderbird users. We hope it and the included deck inspire you to share your knowledge, experience, and problem-solving skills. It’s a great way to get involved with Thunderbird – whether you’re a new or experienced user!
The internet has become a massive web of surveillance, with advertisers and advertising platforms collecting detailed information about people’s online activity. At Mozilla, we believe this information belongs only to the individual and that its unfettered collection is an unacceptable violation of privacy. We have deployed and continue to deploy advanced anti-tracking technology in Firefox, but believe the ecosystem will continue to develop novel techniques to track users as long as they have a strong economic incentive to do so.
We are also deeply concerned by developments in some jurisdictions to restrict anti-tracking features in browsers. In a world where regulators have to balance competing interests, it is dangerous to have advertising and privacy in a zero-sum conflict.
To address these technical and regulatory threats to user privacy while advancing Mozilla’s mission, we are developing a new technology called Privacy-Preserving Attribution (PPA). The technology aims to demonstrate a way for advertisers to measure overall ad effectiveness without gathering information about specific individuals.
The Technology Behind PPA
Rather than collecting intimate information to determine when individual users have interacted with an ad, PPA is built on novel cryptographic techniques designed to protect user privacy while enabling aggregated attribution. This allows advertisers to obtain aggregate statistics to assess whether their ads are working. It does not enable any kind of ad targeting. At its core, PPA uses a Multi-Party Computation (MPC) system called the Distributed Aggregation Protocol (DAP), in partnership with the Divvi Up project at the Internet Security Research Group (ISRG), the organisation behind Let’s Encrypt.
Here’s how it works:
Instead of exposing individual browsing activity to determine who sees an ad, PPA uses mathematics to keep consumer information private. When a user interacts with an ad or advertiser, a record of that interaction is split into two indecipherable pieces on their device – each of which is encrypted and then sent to two independently operated services. Similar pieces from many users are then combined by these services to produce an aggregate number. This number represents how many people carried out an action (such as signing up for a newsletter) after seeing the ad — all without revealing any information about the activity of any individual to either service or to the advertiser. The precise steps are as follows:
Data Encryption: When a user interacts with an ad or advertiser, an event is logged in the browser in the form of a value. That value is then split into partial, indecipherable pieces and then encrypted. Each piece is addressed to a different entity — one to Divvi Up at ISRG and one to Mozilla — so that no single entity is ever in possession of both pieces.
Masking: As an additional protection, the pieces are submitted to Divvi Up and Mozilla using an Oblivious HTTP relay operated by a third organisation (Fastly). This ensures that Divvi Up and Mozilla do not even learn the IP address of the indecipherable piece they receive. The traffic is opaque to Fastly and intermixed with other kinds of requests such that they cannot learn any information either.
Aggregation: Divvi Up and Mozilla each combine all the indecipherable pieces they receive to produce a (still-indecipherable) aggregate value. This means that the data from many users is combined without any party learning the contents or source of any individual data point.
Randomisation: Random noise is also added to each half before being revealed to provide differential privacy guarantees, which mathematically enforce that individual activity cannot be inferred from trends in the aggregate data.
Recombination: Divvi Up and Mozilla then send their indecipherable values in aggregate to the advertiser, leading to a combined statistic of interest. This is an aggregate statistic across all users and does not reveal any information about an individual.
By using these advanced cryptographic methods, PPA ensures that user data remains private and secure throughout the advertising measurement process. At no point does any single entity have access to a specific user’s individual browsing activity – making this a radical improvement to the current paradigm.
Rules of the Road
One of the critical considerations in developing PPA was alignment with privacy legislation, such as the General Data Protection Regulation (GDPR). Here are a few ways that we believe PPA meets the stringent requirements in these laws:
Anonymization: The combination of IP protection, aggregation, and differential privacy used by PPA breaks the link between an attribution event and a specific individual. We believe this meets the high standards of the GDPR for anonymization.
Data Minimization: The information reported by the browser follows strict data minimization practices. The only information included in reports is a single, bounded histogram.
Undetectable Opt-Out: When PPA is inactive, it accepts attribution reports from sites and then silently discards them. This means that sites are unable to detect whether an individual has either enabled or disabled PPA. This measure prevents discrimination or fingerprinting by sites on the basis of the feature’s availability.
Prototype Rollout and User Testing
The current implementation of PPA in Firefox is a prototype, designed to validate the concept and inform ongoing standards work at the World Wide Web Consortium (W3C). This limited rollout is necessary to test the system under real-world conditions and gather valuable feedback.
The prototype is enabled with an Origin Trial — which prevents the API from being exposed in any form to any website unless it’s specifically allowed by Mozilla. For the initial test, the only allowed sites are operated by Mozilla – specifically ads for Mozilla VPN displayed on Mozilla Developer Network (MDN). We chose this approach to ensure sufficient participation to evaluate the system’s performance and privacy protections while ensuring that it is tested in tightly-controlled conditions.
Next Steps and Future Plans
During the prototype test, if a user visits the MDN website on Firefox in relevant markets and comes across an ad for Mozilla VPN that is a part of this trial, all of the technical steps in the previous section will occur in the background to allow us to test the technology. All this while individual browsing activity will never leave the device nor be uniquely identifiable. As always, users have the ability to turn off this functionality in their Firefox settings.
As we move forward, our immediate focus is on refining and improving PPA based on the feedback from this initial prototype. Here’s what to expect in the coming months:
Expansion of Testing: Depending on initial results, we may expand the number of sites involved in the testing phase, carefully monitoring the results to ensure the system operates as intended. Due to ongoing standards development, the prototype uses a non-standardized API and thus will never be exposed in its current form to the web at large.
Transparency and Communication: We are committed to being transparent about how PPA works and how user data is protected. We will continue to provide updates and engage with the community to address any concerns.
Collaboration and Standards Development: Mozilla will continue to work with other companies and public standards bodies to develop and standardise privacy-preserving technologies. Our goal is to create a robust, industry-wide solution that benefits all users.
Ultimately, our vision is to develop, validate, and deploy privacy-preserving technologies like PPA with the goal of ultimately eliminating the need for invasive tracking practices. By proving their viability, we aim to create a more secure and private online environment for everyone. One organisation alone cannot solve these challenges. We invite feedback along the way and we hope that our efforts inspire more organisations to innovate in similar ways. Thank you for your support as we embark on this journey. Together, we can build a better, more private internet.
Update as of August 30, 2024: In recent weeks, as SB 1047 has made its way through the CA legislature, Mozilla has spoken about the risks the bill holds in publications like Semafor, The Hill, and the San Francisco Examiner. In light of the bill’s passage through the legislature on August 29, 2024, Mozilla issued a statement further detailing concerns about the legislation as it heads to the Governor’s desk. We hope that as Governor Newsom considers the merits of the legislation he considers the serious harms that this bill may do to the open-source ecosystem.
In early 2024, Senator Wiener of California introduced SB 1047, also known as the Safe and Secure Innovation for Frontier Artificial Intelligence Models Act. The Act is intended to address some of the most critical, and as of now theoretical, harms resulting from large AI models.
However, since the bill was introduced, it has become the target of intense criticism, mainly due to its potential harmful impact on the open-source community and the many users of open-source AI models. Groups and individuals ranging from Y Combinator founders to AI pioneer Andrew Ng have publicly expressed concerns about the state of the legislation and its potential impact on the open-source and startup ecosystem.
As a champion of openness in the AI and broader tech ecosystem, Mozilla appreciates the open and constructive dialogue with Senator Wiener’s team regarding potential changes to the legislation which could mitigate some of the potential harms the bill is likely to cause and assuage fears from the open-source community. However, due to deep concerns over the state of the legislation, Mozilla, Hugging Face, and EleutherAI sent a letter to Senator Wiener, members of the California Assembly, and to the Office of Governor Newsom on August 8, 2024. The letter, in full below, details both potential risks and benefits of the legislation, options for the legislature to mitigate potential harms to the open-source community, and our desire to support the legislative process.
Open-source software has proven itself to be a social good time and again, speeding innovation, enabling public accountability, and facilitating the development of new research and products. Mozilla has long pushed to Accelerate Progress Towards Trustworthy AI and is highly aligned with the goals of mitigating risks from AI. Our research and a broad swath of historical evidence points to open-source being one of the clearest pathways towards mitigating risk, bias, and creating trustworthy AI.
August 8 Letter to Senator Wiener
The Honorable Scott Wiener
California State Senate
1021 O Street
Suite 8620
Sacramento, CA 95814-4900
Dear Senator Wiener,
We, the group of undersigned organizations, Mozilla, EleutherAI, and Hugging Face, are writing to express our concerns regarding SB 1047, the “Safe and Secure Innovation for Frontier Artificial Intelligence Models Act,” as currently written. While we support the goals of all draftees to ensure that AI is responsibly developed and deployed, and appreciate the willingness of your team to engage with external parties, we believe that the bill has significant room to be improved so that it does not harm the open-source community.
As you noted in your open letter, “For decades, open sourcing has been a critical driver of innovation and security in the software world,” and we appreciate your commitment to ensure that openness can continue. Open source is already crucial to many of AI’s most promising applications in support of important societal goals, helping to solve critical challenges in health and the sciences. Open models reduce the barriers for startups, small businesses, academic institutions, and researchers to utilize AI, making scientific research more accessible and businesses more efficient. By advancing transparency, open models are also crucial to protecting civil and human rights, as well as ensuring safety and security. Researchers, civil society, and regulators can more easily test and assess open models’ capabilities, risks, and compliance with the law.
We appreciate that some parts of SB 1047 stand to actively support open science and research. Specifically, we applaud the bill’s proposal to create CalCompute to provide access to computational resources necessary for building AI and foster equitable innovation.
We also appreciate that ensuring safe and responsible development and deployment of AI is a shared responsibility.
At the same time, responsibility must be allocated in a way that is tailored and proportionate by taking into account the potential abilities of developers and deployers to either cause or mitigate harms while recognizing relevant distinctions in the role and capabilities of different actors. We believe that components of the legislation, as written and amended, will directly harm the research, academic, and small business communities which depend on open-source technology.
We thank your team for their willingness to work with stakeholders and urge you to review several pieces of the legislation which are likely to contribute to such unintended harms, including:
Lack of Clarity and Vague Definitions: In an ecosystem that is evolving as rapidly as AI, definitional specificity and clarity are critical for preventing unintended consequences that may harm the open AI ecosystem and ensuring that all actors have a clear understanding of the expected requirements, assurances, and responsibilities placed on each. We ask that you review the current legislation to ensure that risk management is proportionally distributed across the AI development process as determined by technical feasibility and end user impact.
In particular, we ask that the definition of “Reasonable assurance,” be further defined in consultation with the open-source, academic, and business community, as to exactly what the legislature requires from covered developers as the current definition of “…does not mean full certainty or practical certainty,” is open-ended.
Undue Burdens Placed on Developers: As written, SB 1047 places significant burdens on the developers of advanced AI models, including obligations related to certifying specific outcomes that will be difficult if not impossible to responsibly certify. The developer of an everyday computer program like a word processor cannot reasonably provide assurance that someone will not use their program to draft a ransom note that is then used in a crime, nor is it reasonable for authorities to expect that general purpose tools like open-source AI models should be able to control the actions of their end users without serious harms to fundamental user rights like privacy.
We urge you to consider emerging AI legislative practices and to re-examine how certain obligations within the bill are structured and the likelihood of an individual developer acting in good faith being able to reasonably apply with such obligations. This includes the requirement to identify specific tests and test results that would be sufficient to provide reasonable assurance of not causing or enabling a critical harm, especially as this requirement applies to covered model derivatives.
FMD Oversight of Computing Thresholds: In its current form, the legislation gives the Frontier Model Division (FMD) broad latitude after January 1, 2027, to determine which AI models should be considered covered under the proposed regulation. Given rapid advances in computing, it is likely that in a short time the current threshold set by the legislation will be surpassed, including by startups, researchers, and academic institutions. As such, these thresholds will quickly become obsolete.
We urge you to create clear statutory requirements for the FMD to ensure that the agency regularly updates the criteria for what is considered to be a covered model in consultation with academia, civil society, the open source community, and businesses. As AI advances and proves not to cause “critical harms,” regulators should quickly follow suit to ensure that innovation is not unnecessarily stymied.
Current Definition of Open-Source: As Mozilla research has noted, defining AI open source for foundation models is tricky. However, the current definition of an “Open-source artificial intelligence model,” in the legislation does not include the full spectrum of how researchers and businesses currently release openly available AI models. Today, developers often do so with some legal or technical limitations in place in an effort to make sure their work is used legally and safely. We urge you to broaden the definition and consider working with a body such as the Open Source Initiative to create a legal definition that fully encapsulates the spectrum of openly available AI.
Open-source has been a proven good for the health of society and the modern web, creating significant economic and social benefits. In early 2024, Mozilla and the Columbia Institute of Global Politics brought together over 40 leading scholars and practitioners working on openness and AI – where one of the key findings of the group was that “Openness in AI has the potential to advance key societal goals, including making AI safe and effective, unlocking innovation and competition in the AI market, and bring underserved communities into the AI ecosystem.”
We are strong proponents of effective AI regulation, but we believe that AI risk management and regulatory requirements should be proportionally distributed across the development process based on factors such as technical feasibility and end user impact.
We are committed to working with you to improve SB 1047 and other future legislation. However, as the bill currently stands, we believe that it requires significant changes related to the legislation’s fundamental structure in order to both achieve your stated goals and prevent significant harm to the open-source community.
Sincerely,
Mozilla,
EleutherAI,
Hugging Face

We released Dawnmaker 18 days ago, and I'm due for a report on numbers. Everybody loves numbers, right? Here are ours!
First a little context: Dawnmaker is a turn-based, solo strategy game mixing city building and deckbuilding. Basically, it's like a board game but digital and solo. We've been working on this title for 2.5 years, as a team of two people: myself, doing game design and programming, and Alexis, doing everything art-related. We've had some occasional help from feelancers, agencies and short-term hires, but it's mostly been just us 2. Dawnmaker is our second game, the first one being Phytomancer, a small game we made in 6 months and released on itch.io only.
We did not find a publisher for Dawnmaker — not for lack of trying — and thus had a very limited budget. The main consequence of this is that we skipped the production phase. We had a very long preproduction (about 2 years) and then went straight to postproduction in order to release what we had in a good state. Effects of this decision can be felt in some reviews of the game, complaining about the lack of content. We had big plans for new mechanics, but cut most of these in order to ship.
Marketing on Hard Mode
The second consequence of not having a publisher is that we did all the marketing ourselves. It was hard, not very good and not very efficient, but we did our best. We did not have a well-defined go-to-market strategy, and did things a bit organically. I'm comfortable with Twitter so I started using it, joining some communities like #TurnBasedThursday. I also did a bunch of reddit publications that worked quite well, though none of them went viral. Alexis is more of an instagram person so he handled that, as well as tiktok. Reddit is really the only social network that brought us actual wishlists and sales, the others had no impact that I could see.
Scratch that: YouTube is the platform that actually brought us wishlists and sales. We had a few videos, some by medium-sized youtubers, that brought big spikes in wishlists — see the graph below. And surprisingly, our launch trailer is currently being shown by YouTube on their front page, which is bringing us a nice boost in visibility! But that's pure luck: as far as I know, we have absolutely no control over the YouTube algorithm, and are all subject to its whims.
The spike at launch is free visibility offered by Steam: we did nothing other than making the page public on Steam. I assume it happened because we had tags that work well on Steam: city builder and deckbuilder mainly. At that time, the page only had screenshots and a basic description. No trailer, no demo.
I feel like we got lucky with our marketing. As I told earlier, we had no real go-to-market strategy, we just tried things. I spent a lot of time in the last 3 years reading about marketing, from howtomarketagame.com, GameDiscoverCo and other such sources. Basically I've been applying lessons learned from these sources, trying to make as little mistakes as possible — though we still made a lot of them, like: not having a go-to-market strategy… The reason why I feel we got lucky is that most of the spikes shown above came from unsolicited sources. Nookrium and Orbital Potato just happened to pick up our demo because they saw it during the Deckbuilders Fest. automaton-media.com, a popular Japanese website, made an article about Dawnmaker totally out of the blue — we did not even have a Japanese translation at the time. And when we did send keys of the game to youtubers and streamers, almost none of them responded. I feel like we just made our best to exist, being in festivals and social networks, and then waited for the Universe to notice.
Considering the lack of marketability of Dawnmaker, I'm still pretty proud that we reached Popular Upcoming on the front page of Steam a day before the release. We had a tad less than 6k wishlists when we reached that Holy Grail, and 7029 wishlists when we hit the release button.
Launching into… the neighbor's garden
Pricing the game was difficult. Our initial intention was to sell it for $20. But we never did our production phase, so our content was way too lacking to justify that price point. We decided to lower the price to $15, but then talked about it with a few French publishers. All of them agreed that it should be a $10 game, not because of the game's quality, but because in today's market, that's what players are ready to pay for the content we have. Pricing the game less also meant that players would feel less resistance in buying the game, hopefully leading to more sales, compensating for the money gap. And it would lower their expectations, leading to better reviews. We actually saw that: quite a few comments talk about the lack of content, but still give a positive review thanks to the low price.
Considering all this, here's how Dawnmaker sold:
These are our numbers after 18 days of being on Steam. We're currently sitting on 8.8k wishlists, with a conversion rate of 5.8%. We are getting close to 900 units really sold (total sold minus refunds). These numbers are very much in the range of estimations based on surveys from GameDiscoverCo. We'll be selling about 1k units in the first month, just like anticipated. It's good that we did not do less than that, but it's still far from what we would need to recoup. No surprises here, neither bad nor good.
The game shipped with English, French and Japanese localizations. The Japanese translation came really late in the process, the Steam page coming just 3 days before the release. Bit of a missed opportunity here that we didn't have it before we "went big in Japan" (the automaton-media.com article), I guess? We'll never know! Anyway, here are our sales per country:
Quick side-note: we also put the game on itch.io, where we sold… 2 units of the game!
On a positive note
These numbers are not high, and are not nearly enough to make a studio of 2 financially stable. I intend to write a postmortem of Dawnmaker where I'll go deeper into all our failures. But for now, let's finish this section with more positive things. First, the reception of the game has been quite great! We have 94% positive reviews, with 53 reviews at the time of writing, giving us a "Very positive" rating on Steam, which I am very proud of. It is incredibly heartwarming to see that the game we spent 2.5 years of our lives on is loved by players. We have 50 players who played the game for more than 20 hours, and that's, seriously, so so cool:
And if we did not have a big spike at launch, our players are still playing today:
That's it for the current state of Dawnmaker! We intend to ship a content update by the end of September, adding a bit more replayability, and then we'll likely move on to other projects. Hopefully more lucrative ones!
I'm happy to answer any questions you have, so shoot them in the comments.
Developer Tools help developers write and debug websites on Firefox. This newsletter gives an overview of the work we’ve done as part of the Firefox 129 Nightly release cycle.
Firefox being an open source project, we are grateful to get contributions from people outside of Mozilla, like Sebastian Zartner who added multiple warnings in the Rules view when resize(#1551579) and float related properties (#1551580)are used incorrectly, when box-sizing is used on elements that ignore width / height (#1583894) and when table-related CSS properties are used on non-table-related elements (#1868788). Thanks a lot Sebo!
We’re very happy to report massive performance improvements throughout the whole toolbox: displaying lots of logs in the console can be 60% faster, console reload 12%. 70% less time is spent sending the console messages to the client, opening the debugger got 10% faster, showing the variable tooltip takes 40% less time than before, reloading the debugger 15%, stepping in a new source 17%, reloading the inspector 50% and the network monitor can be used 50% earlier than what it used to be.
How did we achieve such impressive (in my eyes) number you may ask? And the answer is throttling. For a lot of panels, the DevTools server (i.e. the code that runs in the web page) sends events to the client (i.e. the DevTools panel) to indicate when a resource is available, updated or removed. A resource is a broad term and can cover console messages, CSS stylesheets or Javascript sources. We used to send a single event for each update the client wanted to be notified about. The webpage is logging a variable in a 10000 for-loop? 10000 events were sent and consumed by the client. Even if we’d then throttle the resources on the client side to avoid stressing out the UI, we were still paying a high cost for transmitting and receiving this high number of events. In Firefox 129, we now group updates that are made within a 100ms range and only send one event (#1824726), which really improve the cases where we are consuming a lot of resources in a small amount of time.
@starting-style support
Firefox 129 adds support for @starting-style rules:
The @starting-style CSS at-rule is used to define starting values for properties set on an element that you want to transition from when the element receives its first style update, i.e. when an element is first displayed on a previously loaded page.
This makes it super easy to add animation for an element being added to a page, where you would have need to use CSS animation before. Here, when a div is added to the page, it’s transparent and transition to fully opaque in half a second:
The @starting-style rules are displayed in the Inspector, alongside regular rules, and you can add/remove/edit declarations and values too (#1892192). The transition can be visualized and replayed using the animations panel, like any other transitions.
<figcaption class="wp-element-caption">Slowly transition h1background-color from transparent to gold on page load</figcaption>
One thing to be mindful of is that declarations inside @starting-style rules are impacted by order and specificity. This means that with the following rules:
div {
color: red !important;
transition: all 1s;
}
@starting-style {
div {
color: blue;
background: cyan;
}
}
div {
background: transparent;
}
the declaration for color and background in the @starting-style rule are overridden, and there won’t be any visible transition. In such case, as we already do for regular rules, the overridden declaration will have a distinct style that should make it obvious why a propery isn’t being transitionned.
<figcaption class="wp-element-caption">There will be no transition applied to outline-color, as the @starting-style declaration is overridden by the regular one.</figcaption>
Custom properties (aka CSS variables) can also be declared into @starting-style rules and be animated. We thought it could be helpful to display the @starting-style value of a variable in the tooltip that is displayed when hovering a variable name in a regular rule (#1897931)
<figcaption class="wp-element-caption">The new @starting-style section in the CSS variable tooltip makes it easy to understand that the opacity will be transitionned from 0.5 to 1</figcaption>
Invalid at Computed Value Time in computed panel
In Firefox 128, we added an icon next to Invalid At Computed Value Time registered custom property declarations
One of the main advantage of registered property is to be able to have type checking directly in CSS! Whenever a variable is set and doesn’t match the registered property syntax, it is invalid at computed value time. In such case, a new type of error icon is displayed in the rules view, and its tooltip indicate why the value is invalid and what is the expected syntax
https://fxdx.dev/firefox-devtools-newsletter-128/
In this release, we added the same icon and tooltip in the Computed panel, so it’s easier to understand the custom property computed value, be it the registered property initial value, or a valid inherited declaration (#1900070).
<figcaption class="wp-element-caption">--a computed value is picked up from the registered property initial value, as the 1em set on body doesn’t match the expected registered property syntax. --b computed value is the rgb value for the gold color, as picked up by the declaration on body. The h1 declaration is invalid as 10000rem doesn’t match the expected <color> syntax.</figcaption>
Accessibility fixes
If you’re a regular reader of our newsletter, you might remember that we had a big accessibility project at the end of last year, focusing on the most impactful issues we saw in DevTools. The project ended in the beginning of 2024, but there are still smaller things we need to address, so we took some time during this release to squash a few bugs:
prevent losing focus state in Debugger Scopes panel when blurring Firefox (#1843325)
add focus indicator on Debugger Watch expressions panel inputs (#1904339)
properly communicate Webconsole input filter state to screen readers (#1844087)
in the Inspector, add keyboard focus-ability to stylesheet location link (#1844054),flex and grid highlighter toggle buttons (#1901508), shape editor button (#1844264) and the link to container query element (#1901713)
We’re planning another couple-months long accessibility project by the end of the year to fix more issues and add High Contrast Mode support, so stay tuned!
And that’s it for this months folks, Thank you for reading this and using our tools, see you in a few weeks for a new round of updates

With the merging of RFC #3672, the Rust project has selected a slate of 26 Project Goals for the second half of 2024 (2024H2). This is our first time running an experimental new roadmapping process; assuming all goes well, we expect to be running the process roughly every six months. Of these goals, we have designated three of them as our flagship goals, representing our most ambitious and most impactful efforts: (1) finalize preparations for the Rust 2024 edition; (2) bring the Async Rust experience closer to parity with sync Rust; and (3) resolve the biggest blockers to the Linux kernel building on stable Rust. As the year progresses we'll be posting regular updates on these 3 flagship goals along with the 23 others.
Rust’s mission
All the goals selected ultimately further Rust's mission of empowering everyone to build reliable and efficient software. Rust targets programs that prioritize
reliability and robustness;
performance, memory usage, and resource consumption; and
long-term maintenance and extensibility.
We consider "any two out of the three" to be the right heuristic for projects where Rust is a strong contender or possibly the best option, and we chose our goals in part so as to help ensure this is true.
Why these particular flagship goals?
2024 Edition. 2024 will mark the 4th Rust edition, following on the 2015, 2018, and 2021 editions. Similar to the 2021 edition, the 2024 edition is not a "major marketing push" but rather an opportunity to correct small ergonomic issues with Rust that will make it overall much easier to use. The changes planned for the 2024 edition include (1) supporting -> impl Trait and async fn in traits by aligning capture behavior; (2) permitting (async) generators to be added in the future by reserving the gen keyword; and (3) altering fallback for the ! type. The plan is to finalize development of 2024 features this year; the Edition itself is planned for Rust v1.85 (to be released to beta 2025-01-03 and to stable on 2025-02-20).
Async. In 2024 we plan to deliver several critical async Rust building block features, most notably support for async closures and Send bounds. This is part of a multi-year program aiming to raise the experience of authoring "async Rust" to the same level of quality as "sync Rust". Async Rust is widely used, with 52% of the respondents in the 2023 Rust survey indicating that they use Rust to build server-side or backend applications.
Check out the whole list! (Go ahead, we'll wait, but come back here afterwards!)
How to track progress
As the year progresses, we will be posting regular blog posts summarizing the progress on the various goals. If you'd like to see more detail, the 2024h2 milestone on the rust-lang/rust-project-goals repository has tracking issues for each of the goals. Each issue is assigned to the owner(s) of that particular goal. You can subscribe to the issue to receive regular updates, or monitor the #project-goals channel on the rust-lang Zulip. Over time we will likely create other ways to follow along, such as a page on rust-lang.org to visualize progress (if you'd like to help with that, reach out to @nikomatsakis, thanks!).
It's worth stating up front: we don't expect all of these goals to be completed. Many of them were proposed and owned by volunteers, and it's normal and expected that things don't always work out as planned. In the event that a goal seems to stall out, we can either look for a new owner or just consider the goal again in the next round of goal planning.
How we selected project goals
Each project goal began as a PR against the rust-lang/rust-project-goals repository. As each PR came in, the goals were socialized with the teams. This process sometimes resulted in edits to the goals or in breaking up larger goals into smaller chunks (e.g., a far-reaching goal for "higher level Rust" was broken into two specific deliverables, a user-wide build cache and ergonomic ref counting). Finally, the goals were collated into RFC #3672, which listed each goals as well as all the asks from the team. This RFC was approved by all the teams that are being asked for support or other requests.
Conclusion: Project Goals as a "front door" for Rust
To me, the most exciting thing about the Project Goals program has been seeing the goalscomingfromoutside the existing Rust maintainers. My hope is that the Project Goal process can supplement RFCs as an effective "front door" for the project, offering people who have the resources and skill to drive changes a way to float that idea and get feedback from the Rust teams before they begin to work on it.
Project Goals also help ensure the sustainability of the Rust open source community. In the past, it was difficult to tell when starting work on a project whether it would be well-received by the Rust maintainers. This was an obstacle for those who would like to fund efforts to improve Rust, as people don't like to fund work without reasonable confidence it will succeed. Project goals are a way for project maintainers to "bless" a particular project and indicate their belief that it will be helpful to Rust. The Rust Foundation is using project goals as one of their criteria when considering fellowship applications, for example, and I expect over time other grant programs will do the same. But project goals are useful for others, too: having an approved project goal can help someone convince their employer to give them time to work on Rust open source efforts, for example, or give contractors the confidence they need to ensure their customer they'll be able to get the work done.
The next round of goal planning will be targeting 2025H1 and is expected to start in October. We look forward to seeing what great ideas are proposed!
It's been a long hot summer at $DAYJOB and I haven't had much time for much of anything, but I got granted some time this week to take care of an unrelated issue and seized the opportunity to get caught up.
The OpenPOWER Firefox JIT still crashes badly in Wasm and Ion for reasons I have yet to ascertain, but the Baseline Interpreter and Baseline Compiler stages of the JIT continue to work great and are significantly faster than the baseline Interpreter (even in a PGO-LTO build), so I did the needful and finally got them pulled up to the new Extended Support Release which is Firefox 128.
I then spent the last two days bashing out crashes and bugs, including a regression from Firefox's new WebAssembly-based in-browser translation engine. The browser chrome now assumes that WebAssembly is always present, but on JIT-less tier-3 machines (or partially implemented JITs like ours, and possibly where Wasm is disabled in prefs) it isn't, so it hits an uncaught error which then blows up substantial portions of the browser UI like the stop-reload button and context menus. The Fedora official ppc64le build of Firefox 128.0.3 is affected as well; I filed bug 1912623 with a provisional fix. Separately all JIT and JavaScript tests completely pass in multiple permutations of Baseline Interpreter and Baseline Compiler, single- and multi-threaded.
As a sign of confidence I've been dogfooding it for the last 24 hours with my typical massive number of tabs and add-ons and can't get it to crash anymore, so I'm typing this blog post in it and using it to upload its own changesets to Github. Grab the ESR source from Mozilla (either pull a tree with Mercurial or just download an archive) and apply the changesets in numerical order, though after bug 1912623 is fixed you won't need #823094. The necessary .mozconfig for building an LTO-PGO build, which is what I'm using, is also in that issue; it's pretty much the same as earlier ones except for --enable-jit.
Little-endian POWER9 remains the officially supported architecture. This version has not been tested on POWER8 or big-endian POWER9, though the JIT should still statically disable itself even if compiled with it on, so the browser should still otherwise work normally. If this is not the case, I consider that a bug, and will accept a fix (I don't have a POWER8 system here to test against). There are no Power10 specific instructions, but I don't see any reason why it wouldn't work on a Power10 machine or on a SolidSilicon S1 whenever we get one of those.
Comments always solicited, though backtraces and reliable STRs are needed to diagnose any bug, of course. Meanwhile I've got more work cut out for me but at least we're back in the saddle for another go.
Everybody* is on about plans for how to break up Google, so here’s my version. I’m trying to keep two awkward considerations in mind.
Any Google breakup plan has to fit in a tweet. Google will have more total lawyer time over more years to find the gaps in a complicated plan than could ever be invested in making the plan. Keep it simple, or Google will re-consolidate the way that AT&T did. (All right, maybe not fit in a tweet, but at least get it down to one side of a piece of paper.)
Leave Google with the ability to preserve shareholder value. Google is a big company that does a lot of things, so don’t drag it down with pointless micromanagement. Make as few breakup rules as possible but otherwise give them the ability to achieve the important goals in their own way.
The common feature of all Google’s most problematic anticompetitive schemes is control of both the client and the server. For example, the reason that Google Chrome has such weird, clunky in-browser ad features is that it’s made by the same company that also owns YouTube. When the browser company owns a video sharing site with its own ad system, and the company as a whole earns more from YouTube than from open web ads, they have an incentive to develop in-browser ads in a way that a company that didn’t own both YouTube and Google Chrome would not.
So all right, here’s the break-up plan. Should fit on one page. Google is split into two companies, call them clientGoogle and serverGoogle for now.
serverGoogle can’t do clients. The first company, call it serverGoogle, may not sell or rent any hardware, or release any proprietary software that runs outside a serverGoogle data center. Any code that this company makes available outside a data center must be licensed without any limitations on reverse engineering, and distributed in the preferred form for making modifications. No software released by serverGoogle may be a technological protection measure under section 1201 of Title 17 of the United States Code (DMCA anticircumvention).
clientGoogle can’t do servers. The second company, call it clientGoogle, cannot operate any Internet services, except those necessary for the development and distribution of client software.
clientGoogle and serverGoogle can’t communicate confidentially with each other. The two companies can’t enter into an NDA with each other or contract with the same third parties (such as directors or consulting firms) in such a way as to create a confidential communications channel between them. (Consultants will have to pick one company to work for.)
The reason to do it this way is that most of Google’s anticompetitive behavior is based on control of both the client and the server. Splitting client and server would force a flip from an anticompetitive collusion approach to an adversarial interoperability situation. Separating the client and server would address the problems with Google’s browser, now hard-coded to advantage Google’s YouTube, and Google’s ad blocking support designed to bypass Google’s ads. In those two examples, the ads and YouTube would be part of serverGoogle, and the browser and mobile platform would be clientGoogle.
The main monitoring that would be needed is enforcement of rule 3: keep the two companies from colluding. How long does a director or consultant have to sit out before going to work for the other company, that kind of thing. A whistleblower program with rewards big enough to retire on will help.
The two companies would need to coordinate, of course, but any communication would have to happen in open source projects and in organizations such as the Linux Foundation, W3C, IAB, and IETF. Opening up what had been intra-Google conversations to outsiders would not just be an antitrust win, it would also help avert some of the weird groupthink rat holes that all big companies tend to go down.
What about JavaScript? When serverGoogle operates a site with JavaScript, the license for the JavaScript code may not prohibit reverse engineering, the site must provide JavaScript Source Maps, and the terms of service for the site may not prohibit the use of the site with modified JavaScript.
What about servers for version control, CI, bug tracker, and downloads? The servers required to develop and release client software are the one exception to the no servers rule for clientGoogle. (That doesn’t mean clientGoogle gets to run any other servers. For example, if clientGoogle supports a browser with the ability to sync bookmarks, users must configure it to use their account with serverGoogle or some other party, as part of an add account process that users already go through to set up calendar or email accounts today.)
Can clientGoogle run servers for telemetry and in-product surveys? Yes, as long as they’re for the purpose of developing and releasing clientGoogle’s software.
What about Google Fiber? (and other businesses that aren’t client software or Internet services?) Let Google management pick based on what is good for them—we don’t want to micromanage business unit by business unit, just make rules to prevent the known problems.
What about AI? Considering that Google is all on about Integration and Android now? AI is a good example of a win from a client/server split. Mobile devices won’t be stuck talking to a laggy AI server for anticompetitive tying reasons, and Internet services won’t be held back by underpowered on-device AI for anticompetitive tying reasons. Both client and server will be able to make the best implementation choices.
What about the Google Play Store? serverGoogle could run a mobile app store but not release its own apps, which run on the client. clientGoogle could release mobile devices or platforms that enable users to connect to and use an app store, and also release apps.
Could serverGoogle spin off the YouTube service, clientGoogle spin off the YouTube apps, then the service and app companies merge to re-form a standalone YouTube? Yes, if it passes normal FTC merger review. Some post-breakup splitting and trading is going to happen, so the FTC still has to keep an eye on things.
What about my 401(k)? Google is a big part of the stock market, and without anticompetitive collusion they’ll be making less money. But relax. You’re probably invested in an index fund that owns shares in both parasites and hosts—as the legit economy recovers from all this negative-sum value extraction, your total portfolio will do better.
Would this work for [other company] too? Probably not. (Let’s do Google first, which will make the web a lot more fun, then we’ll be on a roll and can move on to whatever other big company is giving everybody grief.)
Don’t cut soup with a knife, people
Here’s how not to break up Google: Some people are suggesting that the breakup plan should be a careful dividing of the big bowl of adtech alphabet soup. (Where on Ari Paparo’s simplified chart do you cut, exactly?) That would be a waste of time—if that’s all you do, Google will just tweak their clients, Chrome and Android, to move the profits out of whatever slice of the soup they have to get rid of, and keep the money flowing into whatever they get to keep.
How breaking up Google could lower your online shopping bill | Ars TechnicaBy overcharging by as much as 5 or 10 percent for online ads, Google allegedly placed a Google tax on the price of everyday goods we buy, Tech Oversight’s Sacha Haworth explained… (Also applies to Google taxes on legit comanies.)
Bonus links
This one important fact about current AI explains almost everythingThe simple fact is that current approaches to machine learning (which underlies most of the AI people talk about today) are lousy at outliers, which is to say that when they encounter unusual circumstances, like the subtly altered word problems that I mentioned a few days ago, they often say and do things that are absurd.
Here is another reason why you should never click on ads to download softwareThe link looks good even though it is listed as sponsored. It shows Google’s official site as the URL. When you check the advertiser, which you can on Google Search, you get confirmation that Google has verified the advertisers identity. All good then?
