Firefox Cookie Policy Shifts, Reflecting Growing User Privacy Concerns

Mozilla’s latest patch to its Firefox browser blocks cookies from domains with which the user has not previously engaged in an effort to make Web browsing more transparent to users, the company said today.

With the new patch, currently only available to developers, a user visiting Amazon could still see the items s/he saved to the cart a few days earlier, functionality which is powered by cookies. But cookies from advertising networks would be blocked unless the user had previously interacted with the particular brand.
