Haven't seen Youtube tabs crash like this in like 6 years, now it's happening several times a day. The Youtube UI is also painfully laggy- when you hover over a video it takes like 3-5 seconds for the player to show up and equally as long when I try to pause the video or change settings. When I open the Youtube front page it just shows a blank dark background for a long while before anything loads. Sometimes Youtube tabs get stuck loading, showing only the video with no UI, no way to pause, no comments or recommended videos and the only way to fix it is to open the page in a new tab. It also sometimes seems like a fucked Youtube tab drags the whole browser down, making any websites load endlessly until I close my Youtube tabs.
It's been like this for a few weeks? months? now, but it's steadily getting worse. I assume it might be Youtube fucking with either uBlock users, or Firefox users, or both
Yeah, YouTube seems deliberately broken for Firefox and/or uBlock and/or the combination (I would never go to YouTube without uBlock so I can't do isolation testing). Nowadays if I want to watch something on YouTube, I just grab the link and download it with yt-dlp to watch it locally in VLC. I can delete the video after.
This has the added benefit of not making my old computer's fans chug, and it prevents YouTube from doing that annoying thing of throwing up a giant thumbnail for another video in the center of the video BEFORE it has finished which blocks vision of the video.
