As the largest browser that doesn’t use Chromium, Firefox has a massive fan base that Mozilla wants to keep happy. Luckily, Mozilla is committed to keeping its browser strong. They just rolled out Firefox Version 121, packed with fantastic features for everyone to enjoy.
What’s new in Firefox 121?
If you’re curious about all the changes in Firefox 121, you can find the full scoop in the release notes provided by Mozilla. The update brings something new for users on every operating system, making it worthwhile to update your Firefox to discover the latest additions.
The highlight of the update is the changes Mozilla made to improve how Firefox displays graphics on Linux:
For Linux users, Firefox now automatically uses the Wayland compositor instead of XWayland when it’s available. This update comes with perks like support for touchpad and touchscreen gestures, swipe-to-nav functionality, per-monitor DPI settings, improved graphics performance, and more.
Keep in mind that due to limitations in the Wayland protocol, Picture-in-Picture windows might need an additional user interaction, usually a right-click on the window, or a tweak in your shell or desktop environment.
If you’re not using Linux, no worries! Windows users can now download the AV1 video extension in Firefox, enabling hardware decoding for AV1 video codecs. For macOS users, Firefox’s Voice Control commands are now available, allowing you to navigate without using a keyboard.

For changes that apply to everyone, Firefox has a new toggle that can automatically underline hyperlinks on a webpage. If you use Firefox for editing PDFs, there’s now a handy floating button that simplifies the removal of any added media in your documents. And, as always, the update includes various security fixes to keep your browsing experience safe.
If you’ve got Firefox already, expect a browser update coming your way soon. And if you haven’t given it a shot yet, now might be the perfect moment to make the switch to Firefox; it’s widely regarded as one of the best browsers for Windows.
