To your average Joe, being “rusty” is not seen as a good thing.1 But readers of this blog know that being Rusty – with a capitol R! – is, of course, something completely different! So what is that makes Rust Rust? Our slogans articulate key parts of it, like fearless concurrency, stability without stagnation, or the epic Hack without fear. And there is of course Lindsey Kuper’s epic haiku: “A systems language / pursuing the trifecta: / fast, concurrent, safe”. But I feel like we’re still missing a unified set of axioms that we can refer back to over time and use to guide us as we make decision ..read more

Today Mozilla Corporation joined an amicus brief in a pair of important Supreme Court cases. The cases consider Texas and Florida laws that prohibit social media platforms from removing hateful and abusive content. If upheld, these laws would make content moderation impossible and would make the internet a much less safe place for all of us. Mozilla urges the Supreme Court to find them unconstitutional. The Texas law, known as H.B. 20, would prohibit large social media sites from blocking, removing, or demonetizing content based on the viewpoint. While it provides an exception for illegal spe ..read more

Highlights URL Paste Suggestions The URL Paste Suggestion feature is now enabled by default in the Nightly version of Firefox.

Today, I’m thrilled to announce that Mozilla Foundation is appointing four new members to its Board of Directors. Over the years, I’ve written about our efforts to expand the Board, most recently in March 2023. Each time, I emphasize that by joining Mozilla’s Board, leaders commit to joining a movement for internet health that spans not just our staff, but also our community.  This year, as Mozilla celebrated its 25th anniversary, we’ve sought leaders to help set up our “next chapter.” When we began our search, we were looking for three new Board members to help grow the scope and impact ..read more

November has been another exciting month for Servo! Our nightly example browser, servoshell, is now easier to navigate, accepting URLs without http:// or https:// both in the location bar and on the command line (@atbrakhi, #30148), and should no longer lock up when run with --no-minibrowser (@wusyong, #30598). Local paths can also be given on the command line, and are still preferred when the path points to a file that exists. Work is now underway to improve our embedding story and prepare Servo for integration with Tauri, starting with precompiled ANGLE for faster initial builds (@atbrakhi ..read more

Welcome to the progress report for October! If you missed the one for September, you’re in luck, because we always try to include a link to the progress report of the previous month in the introduction. Translations All the translations of the app are provided by volunteers from the community. This work is mostly independent from software development and design work. So sometimes it’s easy for us to forget that a lot more people regularly spend time working on the app. Dear translators, thank you for all the work you’re putting into making the app more accessible by translating it to so many ..read more

A special thanks to Justine Tunney of the Mozilla Internet Ecosystem (MIECO), who co-authored this blog post. Today we’re announcing the first release of llamafile and inviting the open source community to participate in this new project. llamafile lets you turn large language model (LLM) weights into executables. Say you have a set of LLM weights in the form of a 4GB file (in the commonly-used GGUF format). With llamafile you can transform that 4GB file into a binary that runs on six OSes without needing to be installed. This makes it dramatically easier to distribute and run LLMs. It also me ..read more
