Used to be a relatively decent extension, but became progressively worse once it began accepting bribes from websites to allow ads to slip through the cracks, while implementing a paid subscription that only allows certain ad filters to work if you are a subscriber. If you really don't like ads, use uBlock Origin as it is 100% free, the team does not want to wipe you clean of your money, and it does a much better job of blocking ads (plus it doesn't accept bribes from ad websites!).
