Works with New Youtube and in tandem with Enhancer for Youtube, however once finished using the utility the x-marks will stay forever, with no option to remove them until needed once again.

Makes browsing YouTube bearable!

normal application, but you need to ask less rights for applications.
does not work instantly. need waiting a ~ two sec. it's not cool. in opera "you cleaver" triggered instantly.
I did not find any analogues in firefox.
thx for this.
p.s. I block more than 2000 channels :D

Fine addon. Waiting Long Time for a addon like this.

It worked. Just tapped the X. Then checked to see the channel was indeed out of my feed.

A nice addon to block Logan Paul ;D
