If you’re on Linux and watch game streams on Twitch/YouTube while gaming, Firefox’s VA-API support matters.
Without it: software decoding uses significant CPU (1080p60 can hit 15-20% CPU on a mid-range CPU). That CPU load competes with your game.
To enable VA-API hardware decode in Firefox:
- about:config → media.ffmpeg.vaapi.enabled = true
- Restart Firefox
- Verify: about:support → Media → Video Decode section should show hardware path
Requires the appropriate driver (Intel: libva-intel-driver or intel-media-driver; AMD: mesa-vaapi or libva-mesa-driver).
Also enable: gfx.webrender.all = true for GPU compositor if not already active.
Result: streaming video drops to near-zero CPU, leaving more headroom for your game. Notable difference on i5/Ryzen 5 class CPUs.
and do tell what on earth does this have to do with the addon you linked?
edit:
this user has been posting a different addon for various purposes every few minutes, starts to smell like some spam attempt. I’d be cautious with the addons
