Version 108.0beta, first offered to Beta channel users on November 15, 2022
Firefox Beta gets updated 3 times a week and as a consequence, the release notes for the Beta channel are updated continuously to reflect features that have reached sufficient maturity to benefit from community feedback and bug reports.
Warning: Features listed here may or may not make a final release of Firefox.
In addition to these release notes, you can follow ongoing development via our @FirefoxBeta Twitter account.
Firefox now supports properly color correcting images tagged with ICCv4 profiles.
The shift+esc keyboard shortcut now opens the Process Manager, offering a way to quickly identify processes that are using too much resources.
