Today, Mozilla published the final build of Firefox 125 as the latest stable release for their popular open-source and cross-platform web browser that introduces new features and many improvements.

Highlights of Firefox 125 include a new URL Paste Suggestion feature that allows users to quickly access URLs copied to the system clipboard without the extra step of pasting them onto the address bar. Firefox will automatically detect that a URL is copied on the clipboard and offer to open it when focusing on the address bar.

This is a welcome productivity enhancement in Firefox, which should shorten the time spent copying and pasting URLs into the address bar. Here’s the URL Paste Suggestion feature in action!

Mozilla Firefox 125 also brings support for highlighting in PDF documents, AV1 codec support for Encrypted Media Extensions (EME) for higher quality playback on video streaming websites, a new option to let users enable Web Proxy Auto-Discovery (WPAD) while configuring Firefox to use the system proxy, and expanded download protection to proactively block downloads from URLs that may not be trustworthy.

Firefox View has been updated as well to display pinned tabs in the Open tabs section, which now features tab indicators so users can see which tabs are playing media and quickly mute or unmute them across windows. Indicators were also added for bookmarks, tabs with notifications, and more.

For users of tab-specific Container add-ons, Firefox 125 lets you search in the address bar for tabs that are open in different containers. For users in the US and Canada, this release will prompt you to save your addresses when submitting an address form so you can more easily complete forms in the future.

Firefox 125 also improves keyboard navigation of the Firefox settings by allowing users to reach the first option in a group of radio buttons where no option is selected with the Tab key rather than reaching every option, as well as to navigate between options with the arrow keys when there’s a selected option.

For Android users, Firefox 125 no longer includes the variant and extension of BCP47 in the Accept-Language header of HTTP requests, which translates to better interoperability with other web browsers.

For web developers, Firefox 125 enables WebAssembly multi-memory by default for more efficient interoperation between wasm modules and better polyfills for upcoming wasm standards like the component model, adds support for Unicode text segmentation to JavaScript, and adds support for the content-box and stroke-box keywords of the transform-box CSS property.

Moreover, it updates the align-content property to work in a block layout to allow block direction alignment without using a flex or grid container, removes the SVGAElement.text method in favor of the more widely-implemented SVGAElement.textContent method, and improves support for the popover global attribute.

It also adds support for contextlost and contextrestored events on HTMLCanvasElement and OffscreenCanvas to allow user code to recover from context loss with hardware-accelerated 2Dcanvas, as well as support for the navigator.clipboard.readText() web API that prompts users with a paste context menu to confirm when attempting to read clipboard data not provided by the same-origin page.

Mozilla will officially announce the Firefox 125 release tomorrow, April 16th, 2024. Until then, you can download the official DEB package for Ubuntu/Debian distros or the tarball binary for other GNU/Linux systems, as well as binaries for macOS and Windows systems from Mozilla’s download server.

Update 3: Firefox 125 is now officially out and we’ve updated the article with all the included features.

Update 2: Firefox 125 is once again available for download and it’s rolling out now to all supported platforms as Firefox 125.0.1.

Update 16/04/2024: Mozilla delayed the release of Firefox 125 and pulled the final build from download. Mozilla says that this is due to the late discovery of a blocker bug. Firefox 125 will be re-released as Firefox 125.0.1 with a fix soon.
