Anthropic's Claude AI model discovered 22 vulnerabilities in Firefox during a two-week collaboration with Mozilla researchers in February 2026, with 14 classified as high-severity. The findings, which represent nearly a fifth of all high-severity Firefox vulnerabilities patched in 2025, demonstrate AI's capability to detect critical security flaws at accelerated speeds, with fixes shipped to hundreds of millions of users in Firefox 148.0.
