Mozilla begins baking new patch to kill tracking cookies

Mozilla has begun to experiment with a new patch for Firefox, which changes whether cookies from third parties are allowed.

Citing Safari as its driving force behind the new approach, the patch will require users to "directly interact with a site or company for a cookie to be installed on their machine".

Currently, a site might call upon elements from other sites, such as advertising units, which in turn store cookies on the user's computer. These can then be recalled at a later date or time to gain an insight into user habits. Mozilla's new patch means that these third party cookies will not be permitted on the user's computer unless they take the time to visit the third party site directly.
