My videos play fine but my side bar is completely gone. No recommended videos, no similar videos, no playlist. Works fine on my other PC.

I have issues with YouTube playback specifically on my work laptop. At home it's fine. It just started one day where videos sometimes fail to auto play and requires multiple refreshes. Even once they get going they often stall out and the progress bar goes all the way back to the beginning so I've gotten in the habit of taking notes of the time before I hit refresh and hope it comes back before I completely lose all interest.

I'd use Piped instead, but it has literally never once worked for me. Videos never load.

The youtube ui is so slow I don't use it, even back when I was using chrome. Thanks invidious!

this is frustating i had to use open with potplayer extension most of times.

They work fine on Brave Browser.

Affected users might have blamed Firefox for the issue. Some may even have switched to a Chromium-based browser, as these worked without any issue.

I've been having issues with YouTube on Firefox for ages, not these issues, different ones. I haven't bothered to test if it's only Firefox that has the problem because I'm not using Firefox for a seamless experience, I'm using because why the fuck would I use anything else on Linux? I won't put google or ms into a Linux environment, even if I don't really care about privacy or whatever, it just feels like mixing oil and water.

Might use another browser like brave or whatever foss solutions are out there, but I'd be surprised if anything like that is better than Firefox.
