It don't work. I get this message on Youtube:

Ad blockers violate YouTube's Terms of Service

It looks like you may be using an ad blocker. Video playback is blocked unless YouTube is allowlisted or the ad blocker is disabled.
Ads allow YouTube to be used by billions worldwide.
You can go ad-free with YouTube Premium, and creators can still get paid from your subscription.

May 30, 2025 update:
It works but all it does is the advertisement goes blank and I have to wait for 30-60 seconds for the video to play again.
I might as well not use this ad blocker and click "Skip" after 15 seconds.
