Firefox to auto-block third-party ad cookies starting with Firefox 22

It has been learnt that Mozilla Firefox browser will soon be automatically blocking third-party cookies starting with Firefox 22, according to the Stanford University researcher who coded the change.

The Firefox latest ability will make it more difficult for online ad networks to track users' activities.

The new Firefox cookie policy was announced by Jonathan Mayer, a graduate student in computer science and law at Stanford University, and one of two researchers at the school who created the HTTP header implementation that signals a user's "No Dot Track" preference, in a blog post and on Twitter.

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.
