Privacy Badger

Privacy Badger is a browser extension developed by the Electronic Frontier Foundation (EFF) to automatically detect and block third-party trackers that monitor user activity across websites without consent. It uses algorithmic methods to identify tracking behavior, such as cookies and fingerprinting, and blocks domains that engage in non-consensual tracking. Key features include sending Global Privacy Control and Do Not Track signals, cookie blocking, click-to-activate placeholders for social media widgets, and compatibility with major browsers like Chrome, Firefox, Edge, and Opera. It is designed for users seeking enhanced privacy online, incentivizing advertisers to adopt better practices while being open-source and free to use.
