If Mozilla Firefox is your favorite Browser, then you may probably start getting to see less advertisement & other forms of Online marketing gimmicks.

Firefox has decided to start blocking cookies from third-party ad networks by default. It will be doing so using a patch submitted by Stanford law student & online privacy activist Jonathan Mayer, says a report in the Verge. The patch is slated for distribution in release 22 of the popular browser.

The report says its behavior is like that of another browser, Apple’s Safari. It will allow sites that users have visited to set cookies on their system, but shall block cookies from third parties like advertising networks unless they already have one on your machine.

Firefox already supports the Do Not Track header.

As all of us know by now, a cookie is a small piece of code that allows a site to store information about an Internet user & also track his movements across the Internet.

News of the patch is already drawing the ire of the ad industry, the report adds.
