The same capabilities as adblock/ublock/etc but with secrecy, less customization/diagnostic options and a price tag. Uses free volunteer-maintained blocklists while charging you.
Steer clear.

i like it

Geweldige tools om al die vervelende advertenties te blokkeren, echt een aanrader, heb zeer goede ervaringen!

amazing... blocks everything under the sun. never thought a free adblocker could be this good. it even blocks yt ads, yt music ads - meaning that you can listen to ad free music for free! insane stuff

GREAT!!!

Don't recommend this extension to anyone since this extension was a copycat.
