To be (intentionally) reductive: the feature leverages a system’s GPU to render web content, rather than the CPU as it does at present. As WebRender is written in Rust and uses a very different design approach, we expect to get stability and performance benefits from this switch.”
“WebRender will replace Gecko’s existing compositor, interfacing with Gecko’s main-thread layout code. What is WebRender? I’ll let Mozilla explain: But until that happens you can force enable WebRender on Linux to get the benefits (like reduced CPU usage) right now, no waiting. A quick and easy way to improve the performance of Firefox on Linux is to force enable WebRender.Īt some point in the near future Firefox will make web render the default rendering engine for all users of the browser, on as many systems as possible.
