Corrine · Sep 12, 2023

Mozilla sent Firefox Version 117.0.1 to the Release Channel.

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)

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. For non-English versions, Fully Localized Versions are available for download.
