Privacy Badger: Automatic Tracker Blocking

"Privacy Badger" is a Firefox add-on that automatically learns to block invisible trackers. It sends out privacy signals to opt-out of data sharing and tracking, replacing some trackers with click-to-activate placeholders. Additionally, it offers protections against tracking from major platforms like Facebook and Google, improving your online privacy experience.

Add-on summary

Privacy Badger automatically learns to block invisible trackers.

Privacy Badger sends the Global Privacy Control signal to opt you out of data sharing and selling, and the Do Not Track signal to tell companies not to track you. If trackers ignore these signals, Privacy Badger will learn to block them.

Besides automatic tracker blocking, Privacy Badger replaces potentially useful trackers (video players, comments widgets, etc.) with click-to-activate placeholders, and removes outgoing link click tracking on Facebook and Google, with more privacy protections on the way.
