Firefox's Latest Version Improves Video Playback, PiP Mode & More

Mozilla has kicked off 2026 with a big update for the Firefox browser. The company has now rolled out the latest version, Firefox 147, with a long list of changes. There are plenty of improvements and fixes included in this update. As of now, the company hasn’t publicly released the patch notes. Once available, you can view it here.

Firefox 147 is out now with several improvements & bug fixes

For now, the latest Firefox version is available via Mozilla’s FTP. If you have Firefox installed on your PC, wait for a few hours, and it should be available for download soon. As a quick rundown, Firefox version 147 brings WebGPU support to Apple Silicon Macs and all supported macOS versions. Besides that, the latest version offers improved video playback performance on PCs with AMD GPUs. Moreover, you will be able to customize shortcuts, automatic picture-in-picture launch, and more after installing the latest Firefox version.

The changes included in the latest version:

• WebGPU support is now enabled for devices with Apple Silicon processors on all supported macOS versions.
• Firefox now supports Compression Dictionaries. This standard has already been adopted by several major sites and can significantly reduce the number of bytes transferred to load a page. This leads to faster page load times, particularly in limited bandwidth situations.
• Improved video playback performance on systems with AMD GPUs by enabling zero-copy playback for hardware-decoded video where supported, bringing them to parity with Intel and NVIDIA GPUs.
• Firefox now supports the Safe Browsing V5 protocol and is migrating from Safe Browsing V4 to the local list mode of Safe Browsing V5 protocol.
• Users with Enhanced Tracking Protection (ETP) set to Strict will have local network access restrictions enabled by default. Firefox will now require users to explicitly allow public websites to access local network resources.
• Firefox now allows you to customize your keyboard shortcuts to replace hard-to-type or hard-to-remember hotkeys, eliminate conflicts with other software, and create your preferred set. Access this experimental new feature by typing `about:keyboard` in the address bar.
• Firefox now supports the Freedesktop.org
• A Picture-in-Picture player window can now optionally be opened automatically for a video playing in a tab when that tab goes into the background.

The list of fixes:

• Fixed an issue that prevented some Windows users from selecting a tab when the cursor was at the top of the screen and the Firefox window was maximized.
• Fixed a bug that made HTTP/3 requests containing non-UTF-8 header values time out or fall back to HTTP/2 after a while.
• A draggable button can now be dragged if initiated from the button itself.
• For Linux GNOME Mutter users, window and rendering surface sizes were updated to match the actual pixel grid so Firefox delivers sharp rendering on fractionally scaled displays regardless of the actual window size.
