Firefox 150 Squashes 271 Bugs Found by Anthropic's AI
Mozilla used early access to Anthropic's Mythos Preview model to hunt down hundreds of vulnerabilities in Firefox.
Mozilla just shipped Firefox 150, and it's a doozy. The release patches 271 security vulnerabilities — all discovered with help from Anthropic's Mythos Preview, an AI model Mozilla got early access to.
That's a staggering number of bugs caught by a single AI-assisted sweep. It underscores just how effective large language models are becoming at finding flaws humans miss in massive codebases.
But Mozilla isn't sounding the AI hype alarm. The Firefox team says emerging AI capabilities won't fundamentally upend cybersecurity in the long run. Their real warning is more near-term: software developers should brace for a rough transition period as AI tools reshape how code gets written, reviewed, and secured.
Translation: AI is already changing the game for vulnerability detection. The industry just hasn't figured out how to keep up yet.
