Why this tool?

Privacy Badger provides protection against website visitor trackers. These trackers come in the form of beacons or invisible pixels and have the goal to collect information about the browser. This data is often shared by third parties and used to create a profile of a particular browser. As minor differences for each user may lead to an individual user, these third parties may even link some of the data to the related individual. Tools like Privacy Badger do not provide guarantees that they block everything, yet can decrease the amount of data greatly.

How it works

Privacy Badger runs as an extension on Chrome, Firefox, and Opera. It reviews requested web pages and disarms them by blocking requests or replace content. These requests could be to addresses that are known for spying and tracking, including web beacons. Privacy Badger can also disable WebRTC, which can reveal internal IP addresses.

Usage and audience

Privacy Badger is commonly used for privacy enhancement. Target users for this tool are general public.
