Firefox Lightbeam: Visualize Your Web Browsing Connections

A Firefox browser extension that visualizes the first and third party sites you interact with on the web, showing potential privacy and security issues with your browsing behavior.

What is Firefox Lightbeam?

Firefox Lightbeam is a free, open source browser extension developed by Mozilla that provides users greater visibility into the relationships between the sites they visit, the third party content embedded on those sites, and the users themselves. By visually mapping site connectivity through an interactive graph, Lightbeam enables users to better understand the potential privacy implications of their browsing behavior.

Once installed on Firefox, Lightbeam will begin logging domains as the user navigates the web, detailing when and where third party content is requested and displayed. This allows the extension to identify site relationships and trackers, building a centered graph that positions the user at its center, the sites they directly interact with in their immediate orbit, and additional third party sites one degree removed.

With this bird's eye map of complex site interaction, Lightbeam gives users actionable insight to make more informed choices around privacy controls and configure browser settings to better align with their comfort level on tracking, advertising, social integration, and aggregate user data collection. While the core focus is on transparency over recommendations, Lightbeam does provide contextual details on each domain and options to break site connectivity.
