If you have used the Firefox web browser for some time and followed its development, you may have noticed the term WebRender being used occasionally in Firefox release notes. Mozilla published a technical and detailed explanation of its WebRender plans in 2017, and it is a good start to get a basic understanding of what WebRender is and how it is designed to improve the performance of the Firefox web browser.
The organization ran a WebRender study in Firefox Nightly in 2018. WebRender is designed to improve the performance of the rendering process in Firefox. It uses the GPU, the graphics processing unit, for that if available, but may also use the CPU if that is not possible. Mozilla started to roll out WebRender for certain configurations some time ago, but it is not obvious if the technology is enabled, and whether it uses the hardware or software acceleration.
In this guide, I'm going to show you how to find out if WebRender is enabled, if hardware or software rendering is used, and how to enable the functionality in Firefox.
Your first option is to use the troubleshooting page of the Firefox web browser. Here is how that is done:
What if you want to enable or disable WebRender, or check if hardware acceleration or the software renderer is used?
To sum it up:
You may want to test different configurations to find out which works best for you. WebRender is not yet available for all hardware configurations and systems; you can check out Mozilla's Wiki page on the status of WebRender.
Now You: Is WebRender enabled on your system?Advertisement
