Version 117.0beta, first offered to Beta channel users on August 1, 2023
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 has added a new dom.event.contextmenu.shift_suppresses_event preference allowing users to disable Firefox forcing the context menu to appear when pressing shift+right-click on a webpage as it can sometimes cause undesirable outcomes on certain sites.
macOS users can now control the tabability of controls and links via about:preferences
Automated translation of web content is now available to Firefox users! Unlike cloud-based alternatives, translation is done locally in Firefox, so that the text being translated does not leave your machine.

Support for credit card autofill has been extended to users with the IT, ES ,AT, BE, and PL locales.

Firefox does not show a screen sharing indicator on Wayland any more. It never worked as well as on other platforms and desktop environments typically provide sharing indicators already.
Web compatibility inspection has been enhanced with our new CSS compatibility tooltip in the Developer Tools Inspector. An icon is now displayed next to properties that could lead to web compatibility issues. When hovered, the tooltip indicates which browsers are not supported and displays a link to the MDN page for the property so the user can learn more about it.
ReadableStream.from is now supported, allowing creation of a ReadableStream from an (async) iterable.
Support for improved CSS nesting is now enabled by default.
