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.
