Firefox/Nightly HDR, RTX HDR, Nvidia Super Resolution & Picture in Picture

Does Firefox Nightly still not support HDR? I like Firefox Nightly and it's customizability. It's 2025 though and it still doesn't support HDR, RTX Super Resolution, and RTX HDR. Super Resolution only works when the video is in fullscreen and only works on Youtube. RTX HDR and HDR isn't supported at all. These features are needed and would improve Firefox Nightly immensely.

As for Picture in Picture, we should be able to have the option to have the video to continue playing after closing the PIP window.

P.S. performance improvements would be great.

HDR worked just fine for a few months, but for some reason doesn't at all now. The nVidia App now shows both Super Resolution and RTX HDR as "inactive" when I watch videos in Firefox. I have no idea why.

Whatever the reason, it's frustrating to finally get support for HDR after waiting nearly 10 years, only to have it ripped away after less than a year... 😕 Mozilla pls

Edit: I just noticed that both RTX HDR and Super Resolution still work when I fullscreen a video--and then stop working when I take it out of fullscreen--which is even weirder. I have a giant monitor so watching videos in fullscreen isn't ideal, but at least it works. Does anyone have a proper fix?

I was having problems in with Youtube, which only worked fullscreen or if I logged out from YT. Seems my problem where YT's "Create" button, which somehow messed up RTX HDR and SR for me in windowed YT.

I used the following filter in uBlock to get RTX working on YT: youtube.com###buttons > ytd-button-renderer.ytd-masthead

Firefox doesn’t support wide color gamut in HDR mode and can’t display HDR photos correctly, yet it can play HDR videos on YouTube — which is quite strange.

I was probably fooled by my OLED monitor. I thought YouTube didn’t show the HDR label simply because they didn’t like Firefox, but after comparing, I found that Firefox indeed doesn’t support displaying HDR videos.

Yes, it lacks support for HDR, which is why we unfortunately need to use Nvidia RTX for now.

RTX HDR and Super Resolution now work in youtube without fullscreen, just paste this into your ublock origin "my filters" tab.
