Edit: I opened another tab in a separate Firefox container and didn't get the pop-up. I believe I read this shit being account-based when the first reports of Youtube's anti-adblock measures started making the rounds and it seems to be the case still
I'm using a smart DNS (ControlD) with adblock and I've never seen those popups everyone keeps complaining about. It also lets me get around F1TV's geo blocking.
google likes to a/b test, you (and me) are in the "no popup yet" group
