I started getting the dreaded anti-adblock pop-ups on Youtube when they started ramping up their efforts a month or so back, and I initially went through the whole rigamarole: First it was just the pop-up, then it was the pop-up with the timer, then the 3-video countdown finally leading to the video player being disabled outright.
Throughout all of this I did the recommended Purging All Caches -> Update Now routine on the Ublock Dashboard at least once a day to keep the pop-ups away, but when it got to the player getting blocked it didn't seem to work anymore. Since I'm on Firefox, I experimented using Containers and found that I could just log in to my YT account on a different container to keep using Youtube until that container started getting blocked.
In the past few weeks I've noticed no issues though apart from having the video player blocked once, which was fixed by purging all caches and updating and I almost forgot about the whole anti-adblock thing altogether. It does seem like YT pages are loading slightly slower than they used to though.
Are you still having issues with Ublock on Youtube or were you even affected at all?
I just updated the filters and it never happened again.
You only had to do that once? In the initial phase I just couldn't get rid of the pop-ups for longer than one session
Do you have uBlock set to auto-update filter lists? It's the first option in the filter list settings, I've had it checked and have yet to see the popup a single time.
r/ublockorigin has pinned the standard guide for anti YouTube warfare. You can refer that.
For me I just had to clear the filter cache and click update. I didn't do anything else.
