New
- We’ve made significant improvements in noise-suppression and auto-gain-control as well as slight improvements in echo-cancellation to provide you with a better overall experience.
- We’ve also significantly reduced main-thread load.
- Firefox will now enforce the
Cookie Policy: Same-Site=laxby default which provides a solid first line of defense against Cross-Site Request Forgery (CSRF) attacks.
Fixed
- On macOS, command-clicking links in Gmail now opens them in a new tab as expected.
- Our newest release fixes an issue where video intermittently drops SSRC.
- It also fixes an issue where WebRTC downgrades screen sharing resolution to provide you with a clearer browsing experience.
- Plus, we’ve fixed video quality degradation issues on certain sites.
- Detached video in fullscreen on macOS has been temporarily disabled to avoid some issues with corruption, brightness changes, missing subtitles and high cpu usage.
Update: To get the update now, select "Help" from the Firefox menu, then pick "About Firefox." Mac users need to select "About Firefox" from the Firefox menu. If you do not use the English language version, Fully Localized Versions are available for download.
