There are several other combinations of compositors and rendering options you can use in Firefox 88 beyond those shown above. That changes if you go type about:config into the address bar and flip the -enabled.

Webrender is, as you can tell by the numbers, not much of an improvement out-of-the-box compared to the old default 'Gecko Basic' compositor. This is how Firefox 88 performs with just Webrender (out of the box performance on Firefox 88), Webrender with EGL rendering, the old 'Gecko Basic' rendering previous Firefox versions defaulted to on GNU/Linux and the old Gecko compositor with OpenGL and EGL enabled: See HOWTO Make Mozilla Firefox Blazing Fast On Linux for benchmarks for some detailed benchmarks of Firefox with Webrender and the old Gecko compositor with and without EGL. That route is still the only options if you are using a Firefox ESR release. Earlier versions required setting a environmental variable called MOZ_X11_EGL=1 to enable it. Flipping that switch makes Firefox render the output form the Webrender compositor using EGL. Mozilla has, luckily, introduced a brand new configuration key for GNU+Linux users using the X display server in about:config called -enabled. Webrender provides dismal performance out-of-the-box on GNU/Linux. It is possible to disable it by setting the special -disabled key to false. It is, as of Firefox 88, enabled even if is set to false in the special configuration interface you can get by typing about:config into the Firefox address bar. Mozilla has made it the default compositor on Linux in Firefox 88. They begun porting it to Firefox as part of a 'project Quantum' in 2016.

Mozilla begun developing a brand new web browser engine called Webrender as part of a independent web browser project called Servo ages ago. Written by 윤채경 (Yoon Chae-kyung) - last edited. Pinch-zoom touchpad support has also been added to the Linux version and there are 11 security fixes with 'high' and 'moderate' impact in this release. It provides dismal performance out of the box which can be improved using a hidden new EGL configuration key. Firefox 88 enables the Webrender compositor by default on GNU+Linux operating systems.
