Firefox 150 introduces UI improvements (split view, enhanced tab sharing, real-time translations, and a built-in PDF editor) and addresses 271 security issues, roughly 40 of which were recorded as CVEs; Mozilla credited Anthropic's Claude Mythos Preview AI with helping find multiple vulnerabilities (including CVE-2026-6746, CVE-2026-6757, and CVE-2026-6758). The update is available now and users are advised to install it, while the article notes that although AI accelerates vulnerability discovery for defenders, it could also benefit attackers if such tools become widely accessible.
