I'm a YouTube Premium user, who only joined recently. Since then, I faced a lot of weird situation in YouTube. Examples are: 1. Not able to scroll after a couple of pages. It just freezes. 2. Not able to watch most of the live. It went frozen within seconds. 3. Sometimes, I can't even put in Comments. It prompted "Return Error", or sth like that. These all only happen with my Premium user account. However, when I go to use another Google account, which isn't a YouTube Premium, all these issues are gone. Moreover, I've already tried a few solutions found in the web, but unfortunately, none worked: 1. Delete all historical data. 2. Disable Hardware Acceleration from the Options page. 3. Disable all Add-ons. 4. Reinstall Firefox. I bet you should be able to see my uninstall survey back in a few days ago. On the other hand, I tried other browsers, like Chrome, Edge and Brave, they don't seem to have these issues. Pls help. Should there be anything I can help, pls advise. Thanks.
