Someone in the Fediverse (I don't know where and who) posted that you have to add the following filters into U-Block Origin.
When done you shouldn't see any anti-adblock-warnings :
Thank you! I was aware of Invideous and I tried that in the past. However, Invideous-redirected videos always seemed to be slow, then disconnected or I experienced buffering.
I'll give the firefox extension for libdirect a try. I tested it and it seems to work flawlessly.
Nice! Im gonna throw these in. I havent had any warnings yet either but the experience of using the official YT site/app without some kind of blocker is horrendous.
