Mozilla has come up with the experimental Collusion add-on for Firefox, which lets users see all the third parties that are tracking your movements across the Web. Creating a new tab, Collusion displays an interconnected graph of sites the user has visited. It also shows the tracking sites which are using third-party cookies to track the user on those sites. Mozilla teamed up with the Ford Foundation to develop the Collusion add-on.

Interested users download the add-on directly from here. This add-on does not require a reboot for Firefox, To get started, click on the Collusion icon in the bottom-right corner of your browser. (You may need to show the Add-on Bar to see the icon.)
