About this Add-on Using interactive visualizations, Lightbeam enables you to see the first and third party sites you interact with on the Web. As you browse, Lightbeam reveals the full depth of the Web today, including parts that are not transparent to the average user. Using two distinct interactive graphic representations — Graph and List — Lightbeam enables you to examine individual third parties over time and space, identify where they connect to your online activity and provides ways for you to engage with this unique view of the Web. How Lightbeam WorksWhen you activate Lightbeam and visit a website, sometimes called the first party, the add-on creates a real time visualization of all the third parties that are active on that page. The default visualization is called the Graph view. How is my information stored?
