Works amazingly well! It blocks like...99.98% of ads, and any ads that do show up, you can click on the little ABP/stop sign, scroll down on the window that pops up, click "Block Element", and it will block it and remember where it was.

Also, they update frequently enough to help keep up to date with any new ads that pop up.
Will be donating some money when I have some spare money (finally, after years [sorry ABP people])
