Mozilla sees increased industry support and user adoption of the Do Not Track feature, and announced new adoption statistics in an event at Internet Week New York.

Mozilla introduced the Do Not Track header last year to give users more control over online tracking by third parties.

Twitter now supports Do Not Track and global user adoption rates continue to increase, Mozilla says.

Current adoption rates of Do Not Track are 8.6% for desktop users of Firefox and 19% for Firefox Mobile users and Mozilla sees the highest percentage of users turning on Do Not Track in The Netherlands, France and the United States.

Mozilla conducted a survey of more than 10,000 Firefox users representing 140 countries. The survey showed that 49% of users surveyed believe their privacy is respected more when Do Not Track is enabled, as opposed to only 12% who feel that way without the setting. Also, the survey found users? trust increases for browsers, publishers and advertisers who support Do Not Track.
