It's a great add-on, no doubt about it. But I have two main issues with it:
a) I've recently noticed that YouTube videos played with this add-on on, won't show as "watched" (or partially watched) on my YouTube account.
b) As someone who doesn't mind adds (I mostly use the add-on for privacy and security, not as an add-blocker) as long as I support the site I'm using (e.g., it isn't part of Big Tech), it's pretty annoying to have to turn-off the add-on site by site, when it'd be much easier and practical if I could just turn it on on a few sites that I don't want to support.

There might be workarounds for these two issues that I'm just unaware of, though. It's a pretty thorough add-on that gets updated all the time.

Edit: the issue "a" has been solved.
