Ghostery is good. Another recommendation is Privacy Badger which I find a bit easier to manage. It's made by the EFF and they have a good description of how it works and how it compares to other extensions.

I did not even know the EFF had a service like this! I use HTTPS Everywhere and love that addon. Thanks for the heads up!
