Firefox 134 improves video playback on Windows

Mozilla has released the first Firefox update of 2025. Firefox 134, Firefox 115.19.0, and Firefox 128.6.0 are already available.

The details:

• Firefox 134 is a smaller release with just a few new features and changes.
• It is also a security update.

Tip: Most Firefox installations are configured to update automatically. You can speed up the process by selecting Menu > Help > About Firefox.

Firefox 134

The official release notes list just a few changes. The new version introduces two new features:

• Support for hardware-accelerated HEVC video playback.
• Touchpad hold gestures support on Linux.

Hardware-acceleration should improve resource usage when that specific type of video is played in Firefox. The Linux feature works by placing two fingers on the touchpad of the computer. This stops any momentum scrolling happening at the time.

Other than that, search engine Ecosia is being added to more regions as an option.

Another change is being rolled out to users from the United States and Canada only. It changes the New Tab layout of the browser. The main difference is that Firefox displays “thought-provoking stories” now there as well, plus the obligatory sponsored stories.

Here is a sample image that Mozilla released that shows the new tab page:

Mozilla lists the applied security fixes on the advisories website. The aggregate severity rating is high and 11 security issues rated high and moderate have been addressed in the update.

Firefox ESR updates

Mozilla maintains two Firefox ESR versions currently. Firefox ESR 115.19.0 is only available for older versions of Windows and macOS.

The current branch version, Firefox ESR 128.6.0 is only available for newer operating systems and versions.

Both release notes pages list just security fixes.
