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

But then others browsers like Firefox will gain popularity… I am okay whatever they do, I never see any ad or ad-blocker blocker and I doubt I will even see any of those.
