The specification has been published as 1st WD already. About http://www.w3.org/TR/2011/WD-tracking-dnt-20111114/ Tracking Preference Expression (DNT) W3C Working Draft 14 November 2011 Currently the proposed DOM Interface for this HTTP header is http://www.w3.org/TR/2011/WD-tracking-dnt-20111114/#js-dom WebIDL [NoInterfaceObject] interface NavigatorDoNotTrack { readonly attribute DOMString doNotTrack; }; The specification might need to be changed. Note that Mozilla has a feature documented differently. https://developer.mozilla.org/en/DOM/navigator.doNotTrack but no real bugs opened for it the closest is https://bugzilla.mozilla.org/show_bug.cgi?id=630357 And IE supports document.navigator.doNotTrack http://www.w3.org/Submission/2011/SUBM-web-tracking-protection-20110224/#dnt-uas 525755 1 ap 2011-12-21 15:55:49 -0800 Note that this is experimentally implemented in Safari now. Just commenting to save someone else the confusion I had when seeing it work. 630163 2 ahf 2012-05-22 03:25:01 -0700 Is anybody working on getting this into trunk? 1890455 3 ahmad.saleem792 2022-08-10 17:16:43 -0700 I think except Safari - no other browser support DND, do we need to extend this functionality or add this? or we can mark this as "RESOLVED WONTFIX" at this point? 1890457 4 ahmad.saleem792 2022-08-10 17:20:17 -0700 I might be wrong here - I believe: https://developer.mozilla.org/en-US/docs/Web/API/Navigator/doNotTrack Based on this - if I do >> console.log(navigator.doNotTrack); across all browsers, I get: Safari 15.6 --> undefined Firefox Nightly 105 --> undefined Chrome Canary 106 --> 1 Although MDN table mentions that Firefox do support it, it might be turned off by default. ___ So I think some browsers do support it. 1892568 5 ap 2022-08-19 17:32:36 -0700 Chrome still supports navigator.doNotTrack, and even has UI to enable it: <https://support.google.com/chrome/answer/2790761>. I don't think that we have any intention of re-adding it, but CC'ing John in case I'm wrong. 1892569 6 wilander 2022-08-19 17:38:57 -0700 You’re right, Alexey.
