Secret services aren’t the only ones collecting data from internet users. Corporate hosts and advertisers are also very interested in the surfing behaviour of private individuals.
In order to sensitise users and show them who is snooping, the Mozilla Foundation has developed a Firefox add-on called Lightbeam, which creates a real-time visualisation of how individual pages and entire commercial networks are tracking users.
In the Graph View, you can see how the visited sites connect to third-party services invisible to the surfer.
The results can be reset or saved at any time. Those who would like to make available their data on an anonymous basis can help the Lightbeam project, which wants to create a comprehensive picture of user tracking.
