Version 90.0a1, first offered to Nightly channel users on April 19, 2021
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.
For macOS users, we're introducing the elastic overscroll effect known from many other applications. A gentle bouncing animation will indicate that you reached the end of the page.
In addition, we added support for smart zoom. Double-tap with two fingers on your trackpad, or with a single finger on your Magic Mouse, to zoom the content below your cursor into focus.
Also on macOS, we are switching to native context menus instead of our custom implementation. Enjoy a consistent look and feel and a better integration with the operating system.
