109.0 FIREFOX RELEASE

January 17, 2023

Version 109.0, first offered to Release channel users on January 17, 2023



NEW

 * Manifest Version 3 (MV3) extension support is now enabled by default (MV2
   remains enabled/supported). This major update also ushers an exciting user
   interface change in the form of the new extensions button.

 * The Arbitrary Code Guard exploit protection has been enabled in the media
   playback utility processes, improving security for Windows users.

 * The native HTML date picker for date and datetime inputs can now be used with
   a keyboard alone, improving its accessibility for screen reader users. Users
   with limited mobility can also now use common keyboard shortcuts to navigate
   the calendar grid and month selection spinners.

 * Firefox builds in the Spanish from Spain (es-ES) and Spanish from Argentina
   (es-AR) locales now come with a built-in dictionary for the Firefox
   spellchecker.


FIXED

 * Various security fixes.


CHANGED

 * Effective on January 16, Colorways will no longer be in Firefox. Users will
   still be able to access saved and active Colorways from the Add-ons and
   themes menu option.

 * On macOS, Ctrl or Cmd + trackpad or mouse wheel now scrolls the page instead
   of zooming. This avoids accidental zooming and matches the behavior of other
   web browsers on macOS.

 * The Recently Closed section of Firefox View now equips users with the ability
   to manually close/remove url links from the list.

 * The empty state messages and graphic components surfaced in Firefox View for
   the Tab Pickup and Recently Closed sections have been updated for an improved
   user experience.


ENTERPRISE

 * Various bug fixes and new policies have been implemented in the latest
   version of Firefox. You can find more information in the Firefox for
   Enterprise 109 Release Notes.


DEVELOPER

 * Developer Information

 * The ability to automatically break when code on the page hits an events
   handler has been available since Firefox 69. Firefox 109 now adds new support
   for the scrollend event. To use this new event breakpoint, open the JS
   debugger and find and expand the Event Listener Breakpoints section in the
   right hand column (learn more).
   
   


WEB PLATFORM

 * The scrollend event is now enabled by default. The event is fired when a
   scroll has completed.

 * Firefox now permanently partitions Storage in third-party contexts
   independent of Storage Access to align with other browsers and provide better
   Web compatibility.


COMMUNITY CONTRIBUTIONS

 * Razvan Cojocaru: Bug 1685648, Bug 1800530
