Hey everyone,
since YouTube started annoying us with their “disable ad blocker” thing, I managed to get rid of it by uBlock Origin and a Tampermonkey script. Yet, the stupid popup is back. To everyone who’s gotten rid of it until now: What did you do? Can you point me to the resources you used? It’s annoying!
Updating your filter lists in uBlock Origin should fix it. Nevertheless, there are better solution for watching YouTube videos without Google’s crappy ads and trackers. There are private frontends like Piped and Invidious, you can use LibRedirect to automatically redirect all YouTube links to your desired frontend. You can also use a native client like FreeTube on Desktop, LibreTube or Tubular/NewPipe on Android, Yattee with this guide on iOS, iPadOS and tvOS, SmartTube on Android TV or this app if you have an LG TV running webOS.
