Please, work with nVidia to add support for RTX Video Super Resolution in Firefox. Nearly 80% of internet bandwidth today is streaming video, and 90% of that content streams at 1080p or lower. Many of us use displays with resolutions higher than 1080p, and Firefox uses basic upscaling techniques, which result in final images that are soft or blurry. PC users also sit close to their screens, which makes the quality of upscaling even more noticeable, and is a good argument for a higher level of processing and refinement.

I prefer to use Firefox for everything I do, but I now feel torn because the difference is so noticeable, and I stream a great deal of video. Again, please, reach out to nVidia and work with them to implement support for RTX VSR. It really makes a difference, and would eliminate any inclination I might have to use a different browser for streaming video.

I've just seen, that it is already there, but it's a hidden feature. To turn in on, go to:

  • about:config
  • gfx.webrender.super-resolution.nvidia (true)

@GASHI have that enabled, I have Super resolution set to 4. I have a 4090. I cannot see any change of quality or it kick in. I've watched Videos, compared Edge & Chrome, you can clearly notice when it kicks in. I can't notice any change in Firefox or Firefox Developer Edition.

Yes it's there already, but does not work in stable, and even in dev it only works for like 60% of YT videos, for some reason.

It used to work on everything when 116 initially came out on the aurora channel, then a recent update broke something and hardly any video gets affected anymore

@A1ucardDarn, you're right. I also just noticed that the about:config entry doesn't do anything at all. Very disappointing.

On my 1440p monitor, super resolution only kicks in when watching youtube videos on 720p. Which is really strange considering that on chrome, it can upscale 1080p to 1440p.

As of 117.01 this still doesn't work properly. For some reason it only works on Youtube itself, but not on alternative Youtube frontends, such as Invidious (in my case,

I'm not sure why it only works on Youtube. It SHOULD technically work on ANY website that plays videos.

As far as I can see it still is not working in 118.0. Is anyone aware that it is even broken?

this tech may converts me to Brave after alllll these years (over a decade for sure), PLEASE make it a some what priority not just an idea!!!

I tried it on both 118.0.2 and freshly installed 119.0 and in both I enabled these configs:


tried YouTube, Twitch and a few other video streaming websites, all work on Brave but not on both FF branches. my GPU is RTX 4060 ti.

I tried it on Brave for the first time today and it is ABSOLUTELY astonishing! the difference is crazy good on 4x scaling!

Currently working sporadically for me in Windows 11.

It will seemingly work for a few videos, then stop working. Restarting Firefox usually fixes it, but it's no fun having to restart my browser so often.
