Privacy Badger
Verified working Aug 3, 2026
A browser extension that learns to block third-party web trackers.
Privacy Badger is a free browser extension from the Electronic Frontier Foundation that detects third-party tracking behavior and blocks or restricts those domains in the browser. It also sends privacy preference signals such as Global Privacy Control and Do Not Track, while offering controls for cookies, widgets, and link-tracking cleanup on supported sites.
Why it stands out
- Uses observed tracking behavior rather than relying only on hand-maintained blocklists.
- Built by EFF, a nonprofit digital rights organization rather than an ad-tech company.
- Designed to work with minimal setup for users who do not want to manage privacy rules manually.
- Blocks ads only when they act as trackers, making its goal narrower than general ad blocking.
- Includes GPC signaling alongside blocking, so it both states a privacy preference and enforces it when ignored.
Good to know
- It is focused on third-party tracking, not all tracking by sites you intentionally visit.
- It does not aim to block every advertisement, so users wanting a full ad blocker may need another tool.
- Browser support is limited to supported extension platforms; unsupported browsers cannot install it directly.
- Some embedded media or widgets may need click-to-activate or manual slider adjustments if blocking affects page behavior.
Under the radar: If a useful embedded widget is blocked, try the extension’s yellow setting for that domain: it can block tracking cookies while still allowing the content to load.
