Mozilla enraged advertisers earlier this year when it said it would block all third-party cookies in its popular Firefox browser. Those same advertisers breathed a collective sigh of relief when Mozilla put those plans on hold to fix a problem in its anti-cookie patch. Now Mozilla is back on the warpath again after finding a potential solution.
Mozilla's Brendan Eich updated his blog today with news of a new cookie software system out of Stanford called Cookie Clearinghouse. According to its Web site, it will "publish block-lists and and allow-lists based on objective, predictable criteria." In other words, it creates lists of good cookies and bad cookies that software vendors can then integrate into their own browsers.
According to Eich, Mozilla will start to test Cookie Clearinghouse integration soon. In the meantime, the previous anti-cookie patch will remain active in Firefox Aurora.
