Title. 156.0 had NVIDIA Video Super Resolution working just fine. 156.0.1 has broken it on my setup. Nothing I have done has brought it back - toggling settings, clearing caches, forcing it on in about:config, etc. The plugin seems to be broken.

Was working just fine for over a year prior.

Latest Stable Firefox 156.0.1 RTX 5080 Driver 596.49 (May '26)

Does not show as working in the Control Panel, and is clearly not working on any video site. YouTube, the BBC, and Twitch were the ones most tested.

Please consider a fix. Thank you.

All of a sudden all of the videos I watch on YouTube with Firefox are defaulting to mute on my Macbook. I haven't made any changes to settings, etc. I don't have a YouTube account so I can't make any changes there anyway. I am having to unmute each video before I watch it.

Playback occasionally lags really hard for 1-2 seconds anytime I watch a video. This goes for all websites, not just youtube. It seems disconnected from buffering as it will happen even when the video is totally loaded. It doesn't lag out any other tabs, and switching to a different tab and back always fixes it (for that moment). I've already tried disabling hardware acceleration and webgl, but nothing changed. It happens about once every minute no matter what. I have a high-end pc, so that shouldn't be the problem. (or maybe it is, and firefox isn't optimized for some bit of hardware that I have) Thank you ^_^

Since the last update, I've been experiencing some issues with Firefox on my MacOS. Visiting website such as beatport.com and spotify.com, for exemple, after click on "play", Firefox does not play the sound or video. The same happened with other websites with webplayers.

The problem is on Firefox version 157.0.x (tested on Macbook Air and Mac Mini, same MacOS version).
