What is Do Not Track?
Do Not Track (DNT) is a mechanism originally proposed and adopted by Mozilla. When turned ON in a browser, the browser sends an additional HTTP Header with every request to the servers. This additional header tells servers that the user does not want to be tracked for behavioral advertisements and other tracking purposes.
All leading web browsers, except Google Chrome, have already introduced the option to change the DNT settings. Users of Firefox, Opera*, Safari and even Internet Explorer can turn-on DNT and enhance their online privacy. Maxthon, a not-so-popular web browser, has gone one step forward to turn-on DNT by default for all users – and there is no option to disable it – after all who wants to disable it! :)
How To Enable DNT in Chrome?
Chrome has not added support for DNT yet, so there is no direct way to enable Do Not Track in Chrome. But, you can install extensions to bring support for DNT in Chrome.
(*Current stable build of Opera does not support DNT. Opera 12 “Wahoo”, which is currently in beta, has option to enable or disable it).
