Privacy Badger was born out of our desire to be able to recommend a single extension that would automatically analyze and block any tracker or ad that violated the principle of user consent; which could function well without any settings, knowledge, or configuration by the user; which is produced by an organization that is unambiguously working for its users rather than for advertisers; and which uses algorithmic methods to decide what is and isn’t tracking.
As a result, Privacy Badger differs from traditional ad-blocking extensions in two key ways. First, while most other blocking extensions prioritize blocking ads, Privacy Badger is purely a tracker-blocker. The extension doesn’t block ads unless they happen to be tracking you; in fact, one of our goals is to incentivize advertisers to adopt better privacy practices. Second, most other blockers rely on a human-curated list of domains or URLs to block. Privacy Badger is an algorithmic tracker blocker – we define what “tracking” looks like, and then Privacy Badger blocks or restricts domains that it observes tracking in the wild. What is and isn’t considered a tracker is entirely based on how a specific domain acts, not on human judgment. (See also.)
When you view a webpage, that page will often be made up of content from many different sources. (For example, a news webpage might load the actual article from the news company, ads from an ad company, and the comments section from a different company that’s been contracted out to provide that service.) Privacy Badger keeps track of all of this. If as you browse the web, the same source seems to be tracking your browser across different websites, then Privacy Badger springs into action, telling your browser not to load any more content from that source. And when your browser stops loading content from a source, that source can no longer track you. Voila!
At a more technical level, Privacy Badger keeps note of the “third party” domains that embed images, scripts and advertising in the pages you visit. Privacy Badger looks for tracking techniques like uniquely identifying cookies, local storage “supercookies,” and canvas fingerprinting. If it observes a single third-party host tracking you on three separate sites, Privacy Badger will automatically disallow content from that third-party tracker.
Red means that content from this third party domain has been completely disallowed.
Yellow means that the third party domain appears to be trying to track you, but it is on Privacy Badger’s cookie-blocking “yellowlist” of third party domains that, when analyzed, seemed to be necessary for Web functionality. In that case, Privacy Badger will load content from the domain but will try to screen out third party cookies and referrers from it.
Green means “no action”; Privacy Badger will leave the domain alone.Do Not Track and Global Privacy Control signals. It just so happens that most (but not all) of these third party trackers are advertisements. When you see an ad, the ad sees you, and can track you. Privacy Badger is here to stop that.
Global Privacy Control (GPC) is a new specification that allows users to tell companies they’d like to opt out of having their data shared or sold. By default, Privacy Badger sends the GPC signal to every company you interact with alongside the Do Not Track (DNT) signal.
What’s the difference? Do Not Track is meant to tell companies that you don’t want to be tracked in any way (learn more about what we mean by “tracking” here). Privacy Badger gives third-party companies a chance to comply with DNT by adopting our DNT policy, and blocks those that look like they’re tracking you anyway.
When DNT was developed, many websites simply ignored users’ requests not to be tracked. That’s why Privacy Badger has to act as an enforcer: trackers that don’t want to comply with your wishes get blocked. Today, users in many jurisdictions have the legal right to opt out of some kinds of tracking. That’s where GPC comes in.
GPC is meant to be a legally-binding request to all companies in places with applicable privacy laws. For example, the California Consumer Privacy Act gives California residents the right to opt out of having their data sold. By sending the GPC signal, Privacy Badger is telling companies that you would like to exercise your rights. And while Privacy Badger only enforces DNT compliance against third-party domains, GPC applies to everyone – the first-party sites you visit, and any third-party trackers they might invite in.
The CCPA and other laws are not perfect, which is why Privacy Badger uses both approaches. It asks websites to respect your privacy, and it blocks known trackers from loading at all.
You can learn more about GPC and your rights here.
At present, Privacy Badger primarily protects you against tracking by third party sites. As far as privacy protections for “first party” sites (sites that you visit directly), Privacy Badger removes outgoing link click tracking on Facebook and Google. We plan on adding more first party privacy protections in the future.
We are doing things in this order because the most scandalous, intrusive and objectionable form of online tracking is that conducted by companies you’ve often never heard of and have no relationship with. First and foremost, Privacy Badger is there to enforce Do Not Track against these domains by providing the technical means to restrict access to their tracking scripts and images. The right policy for whether nytimes.com, facebook.com or google.com can track you when you visit that site – and the technical task of preventing it – is more complicated because often (though not always) tracking is interwoven with the features the site offers, and sometimes (though not always) users may understand that the price of an excellent free tool like Google’s search engine is measured in privacy, not money.
Unlike other blocking tools, we have not made decisions about which sites to block, but rather about which behavior is objectionable. Domains will only be blocked if Privacy Badger observes the domain collecting unique identifiers after it was sent Do Not Track and Global Privacy Control signals.
Privacy Badger does contain a “yellowlist” of some sites that are known to provide essential third party resources; those sites show up as yellow and have their cookies blocked rather than being blocked entirely. This is a compromise with practicality, and in the long term we hope to phase out the yellowlist as these third parties begin to explicitly commit to respecting Do Not Track. The criteria for including a domain on the yellowlist can be found here.research project on classifying third party domains as trackers and non-trackers. We will make occasional adjustments to it as necessary. If you find domains that are under- or over-blocked, please file a bug on Github. documented with the Panopticlick project. Privacy Badger can detect canvas-based fingerprinting, and will block third party domains that use it. Detection of other forms of fingerprinting and protections against first-party fingerprinting are ongoing projects. Of course, once a domain is blocked by Privacy Badger, it will no longer be able to fingerprint you. learning is enabled, Privacy Badger keeps track of cookies that could be used to track you and where they came from, even if you frequently clear your browser’s cookies.
Safari/iOS: Safari seems to lack certain extension capabilities required by Privacy Badger to function properly.
Chrome on Android does not support extensions. To use Privacy Badger on Android, install Firefox for Android.
If you use Google Chrome, you have to install extensions from Chrome Web Store. To install Privacy Badger in Chrome, visit Privacy Badger’s Chrome Web Store listing and click the “Add to Chrome” button there.
Otherwise, you can use the following links to get the latest version of Privacy Badger directly from eff.org:
- Firefox: https://www.eff.org/files/privacy-badger-latest.xpi
- Chromium: https://www.eff.org/files/privacy_badger-chrome.crx
One way is to stop tracking users who have turned on the Do Not Track signal (i.e., stop collecting cookies, supercookies or fingerprints from them). That will work for new Privacy Badger installs.
You can also unblock yourself by promising to meaningfully respect the Do Not Track signal. To do so, post a verbatim copy of EFF’s Do Not Track policy to the URL https://example.com/.well-known/dnt-policy.txt, where “example.com” is replaced by your domain. Posting EFF’s DNT policy on a domain is a promise of compliance with EFF’s DNT Policy by that domain.
Note that the domain must support HTTPS, to protect against tampering by network attackers. The path contains “.well-known” per RFC 5785. Also note that you must post a copy of the policy at each compliant subdomain you control. For example, if you wish to declare compliance by both sub1.example.com and sub2.example.com, you must post EFF’s DNT policy on each domain.downloadable press kit that we’ve put together. enterprise deployment and configuration document. source code is licensed under GPLv3+.

Social media widgets (such as the Facebook Like button) often track your reading habits. Even if you don’t click them, the social media companies often see exactly which pages you’re seeing the widget on. When blocking social buttons and other potentially useful (video, audio, comments) widgets, Privacy Badger can replace them with click-to-activate placeholders. You will not be tracked by these replacements unless you explicitly choose to click them.
Note that Privacy Badger will not replace social media widgets unless it has blocked the associated tracker. If you’re seeing real social media widgets, it generally means that Privacy Badger hasn’t detected tracking from that variant of the widget, or that the site you’re looking at has implemented its own version of the widget.
Firefox: See the Disable or remove Add-ons Mozilla help page.
Chrome: See the Install and manage extensions Chrome Web Store help page.
Edge: See the Add or remove browser add-ons, extensions, and toolbars Microsoft help page.
Opera: Click the menu button in the top left of the window, and then click “Extensions” and then “Manage Extensions.” Scroll until you see Privacy Badger, move your mouse over it, and then click the “X” icon in the upper right. Click “OK” to confirm removal. You can then safely close the Extensions tab.
Privacy Badger should be compatible with other extensions.
While there is likely to be overlap between the various manually-edited advertising/tracker lists and Privacy Badger, unlike adblockers, Privacy Badger automatically learns to block trackers based on their behavior. This means that Privacy Badger may learn to block trackers your adblocker doesn’t know about.
Besides automatic learning, Privacy Badger comes with other advantages like cookie blocking, click-to-activate placeholders for potentially useful tracker widgets (video players, comments widgets, etc.), and outgoing link click tracking removal on Facebook and Google.
Privacy Badger is also a political tool. 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. By using Privacy Badger, you support the Electronic Frontier Foundation and help fight for a better Web for everybody.
It’s fine to use Firefox’s native content blocking and Privacy Badger together.
While there is overlap between Firefox’s tracker lists and Privacy Badger’s protections, unlike list-based blockers, Privacy Badger automatically discovers trackers. This means that Privacy Badger’s automatically-generated and regularly-updated blocklist may learn to block trackers that blockers with human-generated lists don’t know about. And if you enable local learning, your Badger will learn about the trackers you encounter as you browse as well.
