To get rid of the annoying YouTube message (ad blocker are not allowed on Youtube) use this custom filter in uBlock extension
- Open uBlock extension dashboard
- Open my filters tab
- Copy & Paste this code into my filter
- Apply changes and close all tabs

I keep getting that pop-up, I have had ublock installed for years. I haven't done anything special to unlock and just refresh the page and it goes away.
