Mozilla postponed blocking third party cookies in Firefox

Firefox 22 (currently in beta), blocking third-party cookies by default was finally withdrawn by Mozilla few weeks later. The foundation is explained yesterday on the walk back. In February, the announcement of block cookies by default in Firefox deposited by sites that have not been visited by the user provoked an outcry from advertising companies. The Interactive Advertising Bureau, an organization that promotes interactive advertising, spoke of "nuclear attack" against the industry pub. Ultimately, the default blocking disappeared last month in the first beta version of Firefox 22. Sid Stamm, Privacy Officer, had indicated that measure its impact "was not as simple as they had imagined already.”


Brendan Eich, chief technology officer of the foundation, came back yesterday with more detail the reasons for the postponement. Mozilla has faced two problems with this function. On the one hand, false positives, for example, if the user visits the site foo.com, Firefox blocks cookies foocdn.com, and then it is the same company behind the two sites. On the other hand, false negatives, visit once a site does not mean that we agree to follow all over the Internet you are. You can click on inadvertently pub. Mozilla is working to address these issues and it is associated with the Center for Internet and Society at Stanford. Cookie Clearinghouse, a service that centralizes a list of obstacles and other permissions will be tested in Firefox. The default block third-party cookies - which are already operating in Safari on Mac and iOS - so may still take time to be integrated into the final version of the Mozilla browser. Meanwhile, the function can be tested with the version of Aurora.
