I don’t directly use youtube anymore to watch youtube videos, ever. It’s all through the frontends. No ads period, runs smoother, and none of google’s bullshit.

I actually have a redirect extension set up on my browser so that any youtube link just automatically redirects to one of those. But if you don’t want to do that, and just want to use one when you’re having trouble with some particular video, just look at the url and copy-paste the watch?v=******** part of it onto the end of one of those^.
