Mozilla and Google have taken the FTC's advice and give users a Do Not Track option when browsing. The former's Firefox and the latter's Chrome browsers will let users click a box that will then disable the browser's ability to track browsing history that is then used to send out targeted ads. Mozilla will take a header-based approach that its makers believe is more universal and clearer than cookies or blacklists. Users won't need to load ad networks and advertiser lists for this to work, either.
