117.0.1 Firefox Release

September 12, 2023

Version 117.0.1, first offered to Release channel users on September 12, 2023

Fixed

  • Fixed a bug causing links opened from outside Firefox to not open on macOS (bug 1850828)

  • Fixed a bug causing extensions using an event page for long-running tasks to be terminated while running, causing unexpected behavior changes (bug 1851373)

  • Temporarily reverted an intentional behavior change preventing Javascript from changing URL.protocol (bug 1850954).
    NOTE: This change is expected to ship in a later Firefox release alongside other web browsers and sites are encouraged to find alternate ways to change the protocol if needed.

  • Fixed audio worklets not working for sites using WebAssembly exception handling (bug 1851468)

  • Fixed the Reopen all tabs option in the Recently closed tabs menu sometimes failing to open all tabs (bug 1850856)

  • Fixed the bookmarks menu sometimes remaining partially visible when minimizing Firefox (bug 1843700)

  • Fixed an issue causing incorrect time zones to be detected on some sites (bug 1848615)

  • Security fix
