I run it with recommend options + Show video controls and Stop autoplay and I have no issues other than occasional glitches because those two advanced options. What problems do you have?
I was struggling to remember when I posted because it's been a while since I turned it off, but one big one that I do remember was how often it would break 2FA forms that split the inputs into number pairs or similar. To be fair, those forms are stupid, but I have to use enough of them that getting a popup telling me it had truncated the paste to just the first two characters, making me close that popup, paste the number somewhere else and then copy them two at a time (or remember it) was enough to drive me insane on its own.
I started using Apple’s built in 2FA and I have no issues. It’s get filled in automatically. Didn’t had issues before either when I just copied and paste code manually.
