Overview
- Firefox 146 is available now via direct download and the browser’s update function across supported platforms.
- A new Windows 10 backup feature can save passwords, bookmarks and other data locally or to OneDrive without Sync, with optional password encryption and daily automatic saves, and it is rolling out gradually.
- Security notes list at least 13 fixes, including JIT and WebRTC use-after-free bugs that could enable code execution, with reports differing on whether five or six externally reported issues are high severity.
- Firefox adds ML-KEM post-quantum key exchange to WebRTC’s DTLS 1.3 to harden real-time communications against future quantum attacks.
- Platform updates include a dedicated GPU process on macOS to prevent full-browser crashes, native fractional scaling on Wayland for Linux, and an opt-in location choice for EU users, while ESR builds plus Tor Browser and Thunderbird were updated to carry the fixes.
