Recently, Mozilla Foundation has released Firefox 80.0 that comes with several security fixes and performance updates. But this new version didn’t offer too many exciting features; instead, it comes with several security fixes.

Apart from this, the significant Linux change in Firefox 80 is that it’s currently promoting the VA-API acceleration on X11. This significant Linux change can allow the video Acceleration API spearheaded by Intel. 

It is also used by other Mesa drivers with the Gallium3D video acceleration. Mozilla Firefox has updated its new versions on August 25, 2020, soon after all the channels of Mozilla Firefox are updated to the latest versions.
