While it still doesn’t enable AVIF image format support by default, and despite the fact that the beta version shipped with AVIF enabled by default, Firefox 88 promises to enable the WebRender feature by default for users using the KDE Plasma and Xfce desktop environments on Intel/AMD machines.
As you can imagine, this makes your web browsing experience faster and more reliable. Mozilla already shipped WebRender by default for GNOME/X11 users with the Firefox 84 release, but now they are expanding it to more Linux configurations where they believe it?s ready for production use.
