+The whole DNT (Do Not Track) specification has been discontinued. The mechanism design was flawed, because it was a cooperative feature between users, websites, and browsers. The idea is that the user tells the _website_ to not track them, and the _website_ would comply. However, there is no strict enforcement of this policy, so advertisement websites ignored the DNT header and tracked users anyway. The feature is therefore useless. Moreover, it is harmful as it leaves more user [fingerprint](/en-US/docs/Glossary/Fingerprinting) in the header, which can be used to track users even more.

+Browsers are exploring other more enforceable privacy features, such as [global privacy control](/en-US/docs/Web/API/Navigator/globalPrivacyControl), restriction to third-party cookies, and more.
