In recent years, online tracking companies have begun to monitor our clicks, searches and reading habits as we move around the Internet. If you are concerned about pervasive online web tracking by behavioral advertisers, then you may want to enable Do Not Track on your web browser. Do Not Track is unique in that it combines both technology (a signal transmitted from a user) as well as a policy framework for how companies that receive the signal should respond. As more and more websites respect the Do Not Track signal from your browser, it becomes a more effective tool for protecting your privacy. EFF is working with privacy advocates and industry representatives through the W3C Tracking Protection Working Group to define standards for how websites that receive the Do Not Track signal ought to response in order to best respect consumer's choices. 

The following tutorial walks you through the enabling Do Not Track in the four most popular browsers: Safari, Internet Explorer 9, Firefox, and Chrome.
