Unable to disable Firefox gpu usage
I unchecked the "Use hardware acceleration when available" for long time ago but Firefox still just keep using the GPU no matter what.
I've asked a question about Firefox becomes unusable when PC is in high GPU usage before https://support.mozilla.org/questions/1315372 but receive no help so far and turn out this is probably the problem.
Is there any option to completely disable GPU usage in Firefox?
The "Use hardware acceleration when available" is suppose to be the one but it doesn't do anything.

I'm not sure if it disables GPU, but try to set these prefs in about:config:
- gfx.webrender.all = true
- gfx.webrender.software = true
I have `gfx.webrender.software.d3d11` too. Does it do something?

Nope, nothing changed.
Just open new tab and gpu utilization hits 35%.
Simply select some text in this page and it goes 30%.
