This Privacy Badger is working very very well.
My favourite extension at his moment.

Good

I think this is better than any tracker blocker but there should be a way to see what trackers are doing what on the website, highlighting the section it is being used in.

Anyone who defends the right to privacy when casually browsing the web is a digital hero.

This extension is excellent and should be a default for anyone who cares about their privacy (which you should, even if you think you "have nothing to hide"). Privacy is a basic human right, and it has been trampled on time and time again by these awful companies. It is time to fight back.

Support the EFF in any way you can! They are actively defending our rights and fighting to make the internet better. I also recommend their podcast, How to Fix the Internet. Donate if you can, and spread the word.
