You can now activate a Do Not Track feature if you're on Mozilla Firefox. From the Firefox blog: When this option is selected, a header will be sent signaling to websites that you wish to opt-out of online behavioral tracking. You will not notice any difference in your browsing experience until sites and advertisers start responding to the header.

Meanwhile, according to Politico, Sen. Mark Pryor (D-AK) says he's likely to include a do not track element to a privacy bill he's expected to introduce soon.
