About this extension

Privacy Badger automatically learns to block invisible trackers. Instead of keeping lists of what to block, Privacy Badger automatically discovers trackers based on their behavior.

Privacy Badger sends the Global Privacy Control signal to opt you out of data sharing and selling, and the Do Not Track signal to tell companies not to track you. If trackers ignore your wishes, Privacy Badger will learn to block them.

Besides automatic tracker blocking, Privacy Badger replaces potentially useful trackers (video players, comments widgets, etc.) with click-to-activate placeholders, and removes outgoing link click tracking on Facebook and Google, with more privacy protections on the way.

To learn more, see the FAQ on Privacy Badger's homepage.

Why does Privacy Badger need access to my data for all websites?

When you install Privacy Badger, your browser warns that Privacy Badger can “access your data for all websites”. You are right to be alarmed. You should only install extensions made by organizations you trust.

Privacy Badger requires these permissions to do its job of automatically detecting and blocking trackers on all websites you visit. We are not ironically (or unironically) spying on you. For more information, see our Privacy Badger extension permissions explainer.

Note that the extension permissions warnings only cover what the extension has access to, not what the extension actually does with what it has access to (such as whether the extension secretly uploads your browsing data to its servers). Privacy Badger will never share data about your browsing unless you choose to share it (by filing a broken site report). For more information, see EFF’s Privacy Policy for Software.

Release notes for 2023.5.10

Expanded protection for "cookieblocked" (slider set to yellow) domains. These domains are allowed to load without access to cookies, as a compromise to avoid breaking websites. However, sometimes the same domain is used to serve both unobjectionable content as well as obnoxious fingerprinters that do not need cookies to track your browsing. Privacy Badger will now fully block these fingerprinters.
Disabled Google's Topics API by default. The Topics API replaces Federated Learning of Cohorts (FLoC).
You can now see where Privacy Badger observed tracking by a given domain by clicking on the domain name in the list of tracking domains on the options page
Fixed various site breakages
Added Vietnamese translations
Improved translations (Finnish, French, Hebrew, Persian, European Portuguese, Russian, Spanish)
