Privacy Badger is a free browser extension by EFF that automatically learns to block hidden third-party trackers as you browse. It sends Global Privacy Control and Do Not Track signals, blocks trackers that ignore them, and includes features like widget replacement and link cleaning.
Use cases
- block hidden trackers while browsing
- stop companies from spying on me online
- send Do Not Track and Global Privacy Control signals
- prevent browser fingerprinting
- clean tracking parameters from Facebook and Google links
- replace social media widgets with click-to-activate placeholders
- block third-party cookies from trackers
When to choose
- you want automatic, heuristic-based tracker blocking without maintaining blocklists
- you want a privacy extension from a trusted nonprofit (EFF)
- you want GPC and DNT signals sent to websites
- you use Chrome, Firefox, Edge, Opera, or Brave
When to avoid
- you want comprehensive ad blocking with cosmetic filtering (use uBlock Origin instead)
- you need tracker blocking outside the browser
- you need a mobile system-wide privacy solution
