So I hadn't planned on a second post today, but once again I suppose no one told them that? So Mozilla says they patched 271 bugs in Firefox 150. So what aren't they saying?

Business Latest | Mozilla Used Anthropic’s Mythos to Find and Fix 151 Bugs in Firefox by Lily Hay Newman

AI generated summary, Read the full article for complete information.

Mozilla announced that its Firefox 150 release incorporates fixes for 271 vulnerabilities discovered using Anthropic’s Mythos Preview, marking one of the first large‑scale uses of an advanced AI bug‑hunting tool to secure a mainstream browser. While the Firefox team believes AI‑driven vulnerability discovery will not fundamentally overturn long‑term cybersecurity, it warns that developers now face a sudden, intensive “bootcamp” to locate and remediate latent bugs that these models can expose, creating a transitory but demanding period for the industry. Mozilla’s collaboration with Anthropic—outside the broader Project Glasswing consortium—highlights how open‑source software, often maintained by small teams or volunteers, is especially at risk, prompting calls for coordinated effort, resource investment, and broader sharing of tools across the ecosystem to prevent a widening gap where well‑funded organizations protect themselves while others remain vulnerable.

More breathless, but vague praise for #Mythos. Now #mozilla's CTO has come out with a detail-free, hyperbole-laden blog post.

I can't get anything below the surface level on this blog post. Maybe I'm looking in the wrong places.

• The blog post itself contains no links or references (except a link to a prior blog post)
• The Firefox 150 release notes has zero mentions of #Claude, #Anthropic, or Mythos.
• The security advisories in Firefox 150 lists 41 bugs
  • Anthropic is credited exactly 3 times.
  • The blog post says This week’s release of Firefox 150 includes fixes for 271 vulnerabilities identified during this initial evaluation
  • it is not clear why the blog says 271, the release lists 41 issues, and only 3 acknowledge Anthropic
• I've tried looking on Mozilla's bugzilla and I have no access to any bug that is named in those release notes. I can't even see the conversation, much less the code change.

How is someone supposed to put this blog post's claims into context?

Headline of the day:

If you're on Elementary OS, use simply-foxy to "fix" the ugly Firefox because it doesn't fit with the OS.

Two screenshots attached on this post. It's the comparison between the original Firefox browser and after applying simply-foxy.

#Mozilla takes on enterprise #AI providers with #Thunderbolt
Thunderbolt is for businesses that want #opensource, #selfhosted alternative to #MicrosoftCopilot, #ChatGPT, #Claude, and lock-in & security concerns
"The problem we are solving today is one of sovereignty & control," MZLA Ryan Sipes said. "Do you really want to build your AI workflows on top of a proprietary service from OpenAI or Anthropic … having all your internal company data flowing through their systems?"

#Mozilla #Firefox - Merkwürdige Dinge passieren hier - Firefox in der Krise !

Wie lange benutzt Ihr schon Mozilla Firefox? Hat sich für euch gefühlt etwas verändert?

Habt Ihr in den Einstellungen schon mal unter die Motorhaube geschaut oder benutzt Ihr Firefox einfach so wie installiert?

Früher ging das und man war der sicheren Seite. Heute sollte man bei den aktuellen Versionen aber den #Datenschutz und die #Privatsphäre prüfen und entsprechend einstellen.

Wer KI-Funktionen mag, der kann die Einstellungen so belassen. Wer keine #KI und keine #VPN mag, der muss das alles deaktivieren.

Ob man jetzt den #Microsoft #Copilot in Firefox benötigt oder Microsoft-Software überhaupt nicht auf seinem #Linux PC haben möchte, dass muss man auch selbst entscheiden und einstellen.

Die vergangenen Jahre aber, wo Mozilla Firefox grundsätzlich besser war, die sind leider vorbei.
