Version 104.0a1, first offered to Nightly channel users on June 27, 2022
Firefox Nightly gets updated every day and as a consequence, the release notes for the Nightly 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 on our @FirefoxNightly Twitter account as well as read our Nightly Blog.
Subtitles are now available for Disney+ in Picture-in-Picture.
Firefox now supports both the scroll-snap-stop property as well as re-snapping. You can use the scroll-snap-stop property's always and normal values to specify whether or not to pass the snap points, even when scrolling fast. Re-snapping tries to keep the last snap position after any content/layout changes.
