Currently when users visit a website that site may be calling up a number of things from other websites – be it advertising, analytics, behavior tracking, etc. These third party elements drop cookies onto users’ machines, which may be accessed at a later date or time to gather data about users' usage habits. The new mechanism effectively prohibits websites from installing third party cookies onto users’ systems. Users who have the patch installed will have to directly interact with the website or the company "for a cookie to be installed on their machine." This means that up until a user actively interacts with the third party website directly, Firefox will not allow for those cookies to be installed on the user’s system.
