127.0.1 Firefox Release

June 19, 2024

Version 127.0.1, first offered to Release channel users on June 19, 2024

Fixed

  • Fixed an issue where users with a primary password set on their profile could lose their previous session of tabs upon upgrading if they dismissed the primary password prompt (bug 1901899).

  • Fixed an issue where Linux users with accessibility.monoaudio.enable set to true were experiencing slow audio speeds (bug 1900972).

  • Fixed an issue where, in some circumstances, the Firefox installer on Windows failed to complete the installation (bug 1896868).

  • Fixed an issue causing Firefox to incorrectly reject cookies for certain websites (bug 1901325).

Unresolved

  • On Windows, the Private Window icon is displayed in the taskbar even though browser.privateWindowSeparation.enabled is set to false. This will be fixed in the next release (bug 1901840).

  • Under certain conditions, YouTube playback may experience stalling issues. We are actively working on a fix for this problem (bug 1878510).
