YouTube is a cesspool of ads. Without AdBlocker Ultimate watching videos would be unbearable. If you don't have this extension acquire it you'll thank me later.

One of the best extension i have used in terms of ad blocking ............. Hat's off to the makers !!!!! really it helps a lot....

Removed over 100 ads in under an hour after install. Removes all ads so I can focus my attention on the content I wanted.

excellent ad blocker

It saved me from many ads, but important thing is being saved some virus in some ads.
