Windows Phone gets revenge on YouTube from the grave by helping users bypass its ad-blocker-blocker::Windows Phone to the rescue. A lot of YouTube users want to know how to get around the new annoying YouTube pop-up telling viewers to disable their ad-blocker.
Yea I thought I was lucky until a few days ago. Same setup as you; FF, ublock, and pihole. Started with the first message, then this morning I just got the message saying 3 video limit lol.
Thankfully, purging all caches in ublock origin makes it stop for a bit.
