DNT Signal

Feature Status Dev Lead QA Lead Status
Make DNT signal accessible from the navigator global object Landed in Firefox 9 Justin Lebar Ioana Budnar Signed Off

Summary

  • A site that embeds third-party content could force it to honor DNT by suppressing that content when DNT is enabled.
  • Web sites should be able to check if "do-not-track" (DNT) is turned on without needing access to the HTTP stream.
  • A navigator.doNotTrack object in the JS global namespace could signal that DNT is enabled, and its value would match what is sent in the HTTP header.
  • This feature is targeted for Firefox 9.0.
