Firefox Hardware acceleration on Fedora

Firefox supports hardware acceleration on Linux so let's look how to configure it and diagnose potential issues.

Web page rendering

Accelerated web page rendering is supported on both X11 and Wayland backends via. WebRender.

You can check hardware acceleration state at about:support page, look at Compositing row. If there's WebRender, you're running on hardware. If there's WebRender (software) you're on non-accelerated backend.

Web page rendering on Wayland

Hardware acceleration should work out-of-the-box on Wayland. If not please file a bug for it.

Web page rendering on X11

X11 backend can tun in two modes - EGL and XGL.
