Mozilla Used Anthropic's Mythos to Find and Fix 271 Bugs in Firefox

What they did not say is how many of these vulnerabilities were addressed by LLM-created fixes, if any.

As my coworker succinctly put it, "nobody uses Firefox anymore."

I don't know if hundreds of millions of people is exactly, "nobody" but I personally agree that open source software is just going to crush closed source for exactly the reasons we're seeing unfold in front of us; you can audit and correct incorrect behavior for the benefits of all.

Apropos of anything else, I do like that if one of the big bullet points of Mythos is security, that in their list of "preview users" Anthropic chose orgs like Firefox who might have the largest blast radii, and are the most tempting of targets.
