Privacy Badger
Description
Privacy Badger is a free browser extension developed by the Electronic Frontier Foundation (EFF) that automatically detects.
Privacy Badger operates by learning to identify trackers based on their behavior as you browse the web. Unlike traditional ad blockers that rely on predefined lists, Privacy Badger uses algorithmic tracking detection. When it observes a third-party domain tracking your activity across multiple websites without your consent, it blocks that domain from loading further content, effectively preventing covert surveillance and enhancing online privacy. It also attempts to send a Do Not Track signal to websites, blocking domains that disregard this request.
Key Applications
- Blocking Covert Trackers: Automatically identifies and blocks invisible third-party trackers, pixels, and scripts that collect browsing data.
- Enhancing Online Privacy: Prevents cross-site tracking, ensuring your web activity remains private from data brokers and advertisers.
- Enforcing DNT: Actively blocks domains that ignore your browser's Do Not Track setting, adding an extra layer of privacy protection.
Who It’s For
Individuals concerned about online privacy and digital surveillance, users who want to automatically block behavioral advertising trackers, and those looking for a lightweight, list-free tracking blocker.
Pros & Cons
How It Compares
- Versus uBlock Origin: While uBlock Origin is a comprehensive content blocker effective against ads and trackers using extensive lists, Privacy Badger focuses specifically on behavioral tracking by learning and blocking domains that track you across sites. Privacy Badger offers more intelligent, dynamic tracking detection rather than relying solely on static lists.
- Versus Ghostery: Ghostery also blocks trackers and ads, often providing more granular control and insights into specific trackers on a page. Privacy Badger, however, distinguishes itself with its dynamic, list-free learning approach, making it less reliant on human-maintained lists and potentially more effective against novel trackers.
- Versus Brave Browser's built-in blocker: Brave's built-in shields offer robust ad and tracker blocking. Privacy Badger can complement these by providing an additional layer of dynamic, behavior-based tracking detection, especially useful for domains that might not be on Brave's default block lists but are still exhibiting tracking behavior.
