Used it for years, there is a lot you could do with this extension, but I don't even bother to do that and still it removes the annoyance of ads and starves the dataminers who really should do something more ethical with their time anyway than perfecting the technology a totalitarian regime could easily exploit all for earning a quick buck or two.

The number of blocked adds popups are a bit annoying, but for the functionality I endure it as its easily handled.
