Behind the Scenes Hardening Firefox with Claude Mythos Preview

Two weeks ago we announced that we had identified and fixed an unprecedented number of latent security bugs in Firefox with the help of Claude Mythos Preview and other AI models. In this post, we’ll go into more detail about how we approached this work, what we found, and advice for other projects on making […] The post Behind the Scenes Hardening Firefox with Claude Mythos Preview appeared first on Mozilla Hacks - the Web developer blog .

Trustworthy JavaScript for the Open Web

The open web is a critical platform for applications that handle highly sensitive data, from private communications to financial transactions and medical records. Traditionally, servers are trusted to deliver the appropriate code and resources for their web applications to browsers, who then provide a secure and isolated environment for their execution. In some circumstances, this […] The post Trustworthy JavaScript for the Open Web appeared first on Mozilla Hacks - the Web developer blog .

Bitwarden CLI compromised

Bitwarden's CLI got hit by the Checkmarx supply-chain campaign, TypeScript 7.0 beta lands with the Go-rewritten compiler running ~10x faster than 6.0, and pgBackRest lost its maintainer of thirteen years leaving anyone running production Postgres with a real dependency-trust task this week. We've also got Ubuntu 26.04 LTS shipping with TPM-backed full-disk encryption, and Matz dropping Spinel as an AOT path that takes Ruby to native binaries. This week was a good reminder that the tools we depend on are all moving at once. Security, performance, and maintenance aren't isolated threads.

Celebrating computers at Omacon

Do you see the same truth? That's how C.S. Lewis defined the essence of friendship. And that's what we gathered 130 people in New York to honor for Omacon two weeks ago. Seeing the same truth: A love of computers. Bespoke computers. Malleable computers. Our computers. It's the kind of magic you can only really summon in person. We do our best online, but you instantly realize what an impoverished medium it is for creating real connections once you're all together in the same room. So that's what we did. We connected. We shared our work, our passion, and our opinions about all these new Linux vibes. It happened in an absolutely gorgeous venue, generously offered for the occasion by Tobi and his event team at Shopify. The space had an almost comedy-club intimacy, with chairs just a few inches from the podium. Thanks to the single-track format, we made the most of that warm atmosphere. I gave the keynote . I also got to meet Prime, TJ, Bjarne, Spencer, and Vaxry for the first time in person. Which is always a bit odd when you've been working together for a while over the internet. It feels so familiar, but like an unfinished agreement. And then, boom, it's signed with a handshake and a smile. Same with getting to meet and talk to a ton of other Omarchy users from all walks of life. Many were programmers, but plenty were not. Some came from other Linux distributions, but most from either Windows or Mac. Everyone shared a passion for computers, though. Not just as instruments of action, but as delightful environments for play, learning, and connection. It all added up to a massive recharge. I built Omarchy for myself, but sharing it makes it mean so much more. Seeing others enthusiastically embrace it as a starting point for their own Linux adventure is a real boost to the motivation needed to keep making it better. Because there's always more to do: more systems to cover with perfect compatibility, more corners to polish. So that's what we're going to do, together. Make this distro reach more kindred spirits. Entice those who would love a bespoke, kintsugi system, but don't know where to start. It's never going to be for everyone, but that's also why it works as a beacon for those who choose to share the quest.
