Release Notes

Say hello to enhanced Picture-in-Picture! Rewind, check video duration, and effortlessly switch to full-screen mode on the web's most popular video websites.

Passwords generated in Firefox now include special characters, making them more secure.

Importing bookmarks from Safari or a Chrome-based browser? The favicons for those bookmarks will now also be imported by default to make them easier to identify.

The Windows GPU sandbox first shipped in the Firefox 110 release has been tightened to enhance the security benefits it provides.

A 13-year-old feature request was fulfilled, and Firefox now supports files being drag-and-dropped directly from Microsoft Outlook. A special thanks to volunteer contributor Marco Spiess for helping to get this across the finish line!

Mac users can now access macOS Services directly from the context menu.

On Windows, the elastic overscroll effect is now enabled by default, with two fingers scrolling on touchpad or scrolling on touchscreen, you will see a bouncing animation when scrolling past the edge of a scroll container.

AV1 Image Format files containing animations (AVIS) are now supported, improving Firefox' support for AVIF images across the web.

Websites that use window.print() can now be printed in Firefox for Android.

Firefox for Android now supports hardware accelerated AV1 video decoding by default with supported hardware or via fallback to software decoding.

Following up on the work already shipped on macOS and Linux in Firefox 110, GPU-accelerated Canvas2D is now enabled by default for Firefox for Android also.

Firefox 113 introduces a redesigned accessibility engine which significantly improves the speed, responsiveness and stability of Firefox for users of screen readers, as well as certain other accessibility software, east Asian input methods, enterprise single sign-on software and other applications which use accessibility frameworks to access information.

The Awesomebar result menu is now enabled for all users, allowing you to remove history results and dismiss sponsored Firefox Suggest results.

Removed the long-deprecated mozRTCPeerConnection, mozRTCIceCandidate, and mozRTCSessionDescription types. Sites should utilize the non-prefixed variants instead.

Firefox for Android now includes UI improvements to the built-in PDF viewer to make it easier to save PDFs directly.

Firefox 113 adds support for a number of WebRTC features for improved interoperability: RTCMediaSourceStats, RTCPeerConnectionState, RTCPeerConnectionStats ("peer-connection" RTCStatsType), RTCRtpSender.setStreams(), and RTCSctpTransport.

Module scripts can now import other ES module scripts on worklets.

Firefox now supports the color functions from the color (level 4) specification. This includes the lab(), lch(), oklab(), oklch() and color() functions.

Firefox now supports the scripting CSS media query.

The forced-color-adjust property is now supported, allowing authors to opt an element out of color changes in Forced Color Mode for improved readability where the automatically-picked contrasting colors are not ideal.

Firefox will soon behave similar to other browsers when splitting a node (e.g., typing Enter to split a paragraph) and joining two nodes (e.g., typing Backspace at start of a paragraph to join the paragraph and the previous one) when using the built-in editor. When a node is split, the built-in editor creates a new node after the original one, i.e., creates the right node. Similarly, when two nodes are joined, the built-in editor deletes the latter node and moves its children to the end of the preceding node.

This behavior change can be enabled for testing by web apps now with a call of document.execCommand("enableCompatibleJoinSplitDirection", false, "false"). This command is available only when designMode is set to "on" or there is at least one editable element which has the contenteditable attribute, and the built-in editor has not handled the insertParagraph, delete, or forwardDelete command.
