What it does
Privacy Badger is EFF's browser extension for reducing third-party tracking, with privacy signals and controls for blocked embedded content.
Privacy Badger focuses on tracking behavior rather than simply removing every advertisement. Its explanation also describes placeholders for useful embedded widgets and sending Global Privacy Control. Review the extension's site controls if an embedded player or login stops working, and grant only the exception needed for that page. Blocking third-party tracking is a defined browser task; it does not make the first-party site unable to recognize a signed-in user.
