It works well... TOO well. It does a great job at blocking all the stuff it needs to, but compared to other extensions like uBlock, it causes almost every site to break - I have to constantly go in and set a load of stuff to trusted just for even basic site functionality to work. It's an eye-opener; you really get to see what random stuff every site is trying to ping off about you, but at the same time, everything breaks. For this reason it's just become an annoyance to me and I've gone back to uBlock.
