If you're using ad blockers like AdBlock or uBlock Origin, or privacy tools like Ghostery, you've likely heard of Privacy Badger from the Electronic Frontier Foundation (EFF).
This free browser extension for Chrome and Firefox automatically blocks trackers and ads that collect your personal data. Unlike similar tools rooted in AdBlock Plus, Privacy Badger takes a unique, intelligent approach. Here's what sets it apart.
Traditional ad blockers rely on blacklists of known ad-serving URLs. Privacy Badger skips blacklists entirely. Instead, it learns from your browsing by analyzing domains that track you despite your Do Not Track (DNT) signal.
It also maintains a 'yellow list' of sites known to ignore DNT requests. These get cookie blocking rather than full domain blocks, allowing first-party services like Google to function smoothly.
