As we posted earlier, Google has released an extension for Google Chrome users to opt-out of personalized advertising and tracking. Chrome users can install this extension from here to disable online behavioral advertising (OBA).
Google says, "We are building on this work by allowing you to permanently opt out of ad tracking from all companies that offer opt-outs through the industry self-regulation programs. [...] (by installing this extension) You may see the same ads repeatedly on particular websites, or see ads that are less relevant to you.".
Mozilla has also announced a "Do Not Track" mechanism, though that uses a different approach and send user’s preference via HTTP headers. Read more about it here.
