Mozilla is submitting its do-not-track capability as a draft specification to the IETF for review. The do-not-track (DNT) feature is built into the new Firefox 4 Web browser, which is currently at its first release candidate stage (RC1).
DNT is an effort to provide both Web users and advertisers with a mechanism to opt in or out of behavioral tracking and other online data collection.
Other browser vendors, including Google Chrome and Microsoft's IE, are also implementing their own versions of capabilities to prevent tracking. But in contrast to some of the techniques rival browsers are exploring, Mozilla is aiming to convey users' privacy intentions directly to ad networks and websites.
