Lightbeam is a plugin for the Firefox browser that provides visualization of the parties that interact with you online everyday. Mozilla is now providing end users with the ability to see and comprehend who is tracking their web surfing with Lightbeam. Lightbeam for Firefox works: Visualize the Web. As your visualization grows, you can take a closer look into the relationships between the various first and third party sites that are stored in your data. You can also reset or save your data. Call it a Wizard of Oz moment for the Web, where users can collectively pull back the curtain.”]
