The folks at the Guardian released a Firefox addon recently. Called Collusion, it silently tracks third party sites that track users across multiple sites. I’ve run it for something like two days so far, and its depressing how I’ve littered my trail all over the web. The UI is very nicely done, and highlighting an icon shows all the sites it connects to and greys out the rest.
