Unable to use NVIDIA GPU with Firefox

Firefox Kraschar och långsam prestanda

I have tried for several days to get Firefox to use this GPU; I cannot. Chrome, and Edge use this GPU without issues.

I am using Firefox 151.0 (64-bit) 20260516144017 on Windows 11 Pro 25H2, 26200.8457 Nvidia RTX 2000 Ada Generation Laptop GPU with latest driver: NVIDIA RTX Driver Release R595 U4 (596.36) Tue Apr 28, 2026.

Windows > System > Display > Graphics > Firefox GPU preference: High Performance (NVIDIA RTX 2000 Ada Generation Laptop GPU)

Firefox Settings: General > Performance: 

unchecked Use recommended performance settings
 checked    Use hardware acceleration when available

My latest combination of settings are:

gfx.webrender.all = true gfx.webrender.force-disabled = false

webgl.default-low-power = false webgl.disable-wgl = false webgl.disabled = false webgl.enable-prototype-webgl2 = true webgl.force-enabled = true

I have tried several combination of settings to no avail.

I always get: about:support > Graphics > Compositing: WebRender (Software).

Any help is very appreciated -- thank you.
