This could be related to trying to block ads on YouTube; they seem to be retaliating if they detect an ad blocker.

No 1. I have YouTube Premium, so I don't have ads 2. I have AddBlocker disabled on the YouTube website anyway

• I've noticed that tabs with YouTube open get corrupted after a while.

When I create a new tab, everything is fine.

But after a while, it starts to get corrupted.

+ When I had background music on YouTube, after +/- 30 minutes, subsequent songs start to load longer.

So I think there's a problem with Firefox's RAM management, which is especially noticeable on YouTube when I don't refresh the tab for a long time.

• In Chrome 1, the YouTube tab could use up 1GB+ of RAM, but it's not a problem for me as long as it works well.

I don't know how Firefox handles it, but it clearly doesn't handle it very well.

This has been a problem for a while, but not a deal breaker. UNTIL 146.0 was installed this week. I can MAYBE watch 1 YouTube video, and then the system loses it's mind. Clearing the cache doesn't seem to help. Waiting (overnight say, with NO YT videos in tabs - even embedded video) MIGHT give Firefox time to do garbage collection. But this is getting stupid.

I am now keeping Chromium open just for YouTube. At some point I'm going to wonder why I just don't give up and use Chromium or Brave or ...

I've opened an issue at support (though I wasn't able to login via GitHub) but how do we get this fixed. As I said, this has been an issue for a while. Maybe it doesn't impact people who have a gaming PC with a ton of memory, but that isn't the case here.
