Visualize who's tracking you in real time. To get started, click on the Lightbeam icon in the bottom-right corner of your browser. (You may need to show the Add-on Bar to see the icon.)
Lightbeam (formerly Collusion) is an experimental Firefox add-on which enables you, for the first time, to see all the third parties that are tracking your movements across the Web.
Lightbeam will show, in real time, how that data creates a spider-web of interaction between companies and other trackers.
Lightbeam is cross-platform and it works on Mac OS X, Windows and Linux.

- This version is compatible with Firefox 34 and later. It also removes the "contribute data" option since the data was no longer used.
