I tried to watch a youtube livestream today and it failed to play. Non-live videos on youtube are playing, even the same videos watched as VODs after the stream ends, but the livestreams are providing "Your browser can't play this video" errors.

Simultaneously, I'm noticing that some videos on Reddit (such as embedded tiktok videos) are stuck with a circling ring and won't play. At least some of the same videos will play on Tiktok (when I can find them).

ALSO, when I try to watch videos on my Nebula subscription, I'm getting a "This video could not be loaded: 4" error code. ANY video on Nebula.

What the heck gives?!

Does it still happen in a new profile? An easy way to test a new profile is to install Developer Edition and see if it happens there or refresh your existing profile.

Install the Media Feature Pack if applicable.

Does it still happen in Troubleshoot Mode?

"Media feature pack" isn't showing up as an option, but I do have "Windows Media Player Legacy" installed. Yes, the issue does occur in troubleshooting mode - at minimum, the Nebula and livestream issues.

It does *not* happen in a new profile! Does that mean it may be an issue with one of the add-ons or extensions I have installed? Odd... I'd have expected Troubleshooting Mode to resolve the issue if that was the case.

Okay, I refreshed my profile and that seems to have fixed it.

I am having the same issue but launching Firefox in a safe mode or with a new profile does not fix it.

Also, Firefox throws a ton of the following error:
