Unable to view streams/YouTube quality issues

more options

Hi all, I've been having this issue for a while. I am unable to view streams on YouTube or Twitch (Twitch will show streams as offline, whereas YouTube will not even show streams), and I have encountered a new issue where YouTube allows only 360p on videos. I have used the HTML5 Video Capability Test and seem to have an issue in that department (images attached). Even in troubleshooting mode, the issue persists. Any help is appreciated.

Can you show what happens with this stream? https://www.youtube.com/watch?v=bXZLTPV6c-Y

It works for me. see screenshot What OS? What security software are you running?

The link you sent me is a video, not a stream (stream has ended since your message was sent). It works as normal, and the chat replay is seemingly available (can't find a spot where a message is sent, but the chat updates as I scrub through the video).

I am running Firefox 123.0.1 (64-bit) and Mac OS Sonoma 14.3.1.

I am not running any external security software, and it is not uBlock Origin, as the issue was not solved when I switched to Troubleshooting Mode.

Yes! Thank you so much, I didn't know that this was a thing.
