Lightbeam extension for Firefox is no longer supported

Mozilla ended official support of the Lightbeam extension in October 2019 and has no plans to resume maintenance of it in the future.

Starting with Firefox 70, you can use Enhanced Tracking Protection in Firefox for desktop to discover what trackers have been detected blocked by Firefox.

History

Lightbeam, which was first published as an experimental release named Collusion, is an extension for Firefox and was released by Mozilla in 2013 to help users understand the array of first and third party companies people interact with every day across the Web.

Once installed, Lightbeam created a real-time visualization of the websites you visit and all third-party trackers active on those pages.

When the tracking reports were integrated with Firefox 70 as part of the Enhanced Tracking Protection in Firefox for desktop, Mozilla decided to end official support for the Lightbeam extension.
