Privacy Badger provides a useful option of preserving your privacy when you are browsing. Instead of keeping lists of what to block, Privacy Badger learns by watching which domains appear to be tracking you as you browse online and sends the ‘Do Not Track’ signal. If trackers ignore your wishes, your Badger will eventually block them, once it sees the same tracker on three different websites. Besides automatic tracker blocking, Privacy Badger removes outgoing link click tracking on Facebook, Google and Twitter, with more privacy protections on the way. It is available as an extension on multiple platforms such as Chrome, Firefox, Safari and Opera.
