As privacy concerns online are becoming more and more public, Mozilla is looking to take the industry lead with a “do not track” browser feature. This feature would allow Firefox users to automatically opt-out of any third-party ad-based tracking.
How would this work? A user would click to every new page in their search session through a “do not track” HTTP header. And Mozilla hopes that this system becomes a universal method for safer and more anonymous web browsing.
The problem with this feature is that not only would users have to opt into this, but the actual sites would too. And while major sites will probably adopt these features, the sites you might be the most nervous about abusing your information are probably never going to.
