Collusion – See who’s tracking you online

Collusion is an experimental add-on for Firefox and allows you to see all the third parties that are tracking your movements across the Web. It will show, in real time, how that data creates a spider-web of interaction between companies and other trackers.

A neat demo/datavisualization is also available, in case you don’t want to install the add-on or if you’re running an other browser.
