Firefox to auto-block third-party ad cookies by summer
Mozilla will automatically block third-party cookies starting with Firefox 22, which is slated to ship this summer, according to the Stanford University researcher who coded the change.
The move, which will make it more difficult for online ad networks to track users' activities, was only the latest skirmish in a war between advertisers and some browser makers.
Mayer kick-started the change last December when he submitted code to the Bugzilla bug-tracking database operated by Mozilla. It was Mayer's first contribution to the open-source Firefox.
Mozilla has added the cookie change to Firefox's "Nightly" channel, the browser's roughest-edged version. Unless the modification is sidetracked or Mozilla changes its mind, the new policy will first appear in a final release of Firefox on June 25.
