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.
