Automatic tracker blockers
Privacy Badger is an extension by the EFF that monitors third-party trackers loaded with web content. It blocks trackers once they appear on different sites. It does not block advertisements in the first place, but since a lot of ads are served based on tracking information these are blocked as well. For more information on the mechanism, see its FAQ.
Disconnect is a open source project aimed at stopping 2,000 third-party sites from tracking a user. It encrypts data sent to popular sites and claims to loads web pages 27 percent faster. Disconnect shows its users, in real time, how many tracking attempts from Google, Twitter, Facebook, and more are stopped. It categorizes tracking attempts into advertising, analytical, social, and content, which makes it easy to monitor how one is being tracked.
Disconnect can also stop side-jacking, which utilizes stolen cookies to steal personal data. It is easy to use and well supported.
AdNauseam is a lightweight browser extension that blends software tool and artware intervention to fight back against tracking by advertising networks.

TrackMeNot periodically issues randomized search-queries to popular search engines and helps you hide your real ones in a cloud of 'ghost' queries.
