Privacy Badger is an intelligent tracker blocker created by the Electronic Frontier Foundation (EFF). Unlike traditional blockers, it learns to block invisible trackers automatically as you browse, protecting your privacy without breaking websites.
Privacy Badger uses a unique algorithmic approach to block trackers:
