Is Lightbeam safe?

Clean risk

Lightbeam records visited site hosts and third-party request hosts in local browser storage for its tracker map.

Lightbeam listens to web responses and tab updates across all URLs, then stores first-party hostnames, third-party hostnames, request times, favicons, and optional Firefox container IDs in IndexedDB. The reviewed code keeps these records in local extension databases rather than sending them to a remote service.
