Google Adds "Do Not Track" Feature to Chrome

Most browsers already have something like that

Google has added a Do Not Track privacy option to Chrome's developer channel, though it's late to the party compared to other browsers.

When Do Not Track is enabled in a browser, it signals to Websites and to advertisers that the user doesn't want to be followed around the Web for ad targeting purposes. Ad networks and sites aren't required to comply, but several of them do, and the U.S. government is now pressuring more companies to play along, including Google.
