Privacy Badger
Privacy Badger is a browser extension that automatically learns to block invisible trackers. Instead of keeping lists of what to block, Privacy Badger learns by watching which domains appear to be tracking you as you browse the web. If a domain appears to be tracking you across multiple sites, Privacy Badger will automatically block it from loading any further content in your browser. Privacy Badger is developed by the Electronic Frontier Foundation (EFF), a leading nonprofit organization defending digital privacy, free speech, and innovation.
