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 had this code saved and had suggested it to others before but now I didn't take my own advice and had been struggling with those pop-ups for the past few days. I hope this solves it.
EDIT: Doesn't work. Still got the popup despite having all other extensions disabled and uBlock on default settings
