    navigator.doNotTrack Redirect 1

    « DOM Reference

    Summary

    Returns the user's do-not-track setting. This is "yes" if the user has requested not to be tracked by web sites, content, or advertising.

    Syntax

    dnt = navigator.doNotTrack;
    

    Note that navigator.doNotTrack is not the value sent for the do-not-track header.  When the do-not-track header sends "1", navigator.doNotTrack is "yes".  When the header is unset, navigator.doNotTrack is "unspecified".  When the header sends "0" (currently unsupported in Firefox), navigator.doNotTrack is "no".

    Example

    dump(window.navigator.doNotTrack); 
    // prints "yes" if DNT is enabled; otherwise this is "unspecified" in Firefox
    

    Specification

    The Tracking Preference Expression (Working Draft) is based on an earlier version of this specification where navigator.doNotTrack is the value sent for the do-not-track header.
