Fixed

• Improved overall stability by fixing crashes related to browsing, graphics, and accessibility features. (Bugs 2001160, 1998185, 1998188)
• Fixed an issue where fingerprinting protection caused incorrect font rendering on popular websites. (Bug 2000429)
• Fixed crashes related to media playback and GMP process shutdown. (Bug 2002697)
• Fixed an issue where desktop profile shortcuts were being unintentionally removed when changing copied profile settings. (Bug 1998209)
• Improved sidebar text contrast when using vertical tabs with certain themes. (Bug 2006091)
• When restoring from a backup, the restore success message will appear over the new tab page instead of one of the tabs restored from a backup, to avoid cases where the restored tab canceled the restore success message. (Bug 2003307)

Unresolved
On Windows, clicking tabs may not work at the very top of the screen when Firefox is maximized on a second monitor. We’re working to fix this in a future release. (Fixed in 147.0)
