Firefox 22 will by default, so-called third-party cookies to block on the condition that the installers of these cookies and is not the user visited. The change in Mozilla’s browser must have the privacy benefit, but from the ad industry sounds like criticism.

Developer Jonathan Mayer has to the source code of Firefox a patch added to the browser automatically cookies, blocking other urls in the website visited. These third party cookies are mainly in the form of tracking cookies used by advertising companies to track the surfing habits of internet users. The patch of Mayer would in Firefox 22 should be included.

Firefox is not the first browser which third party cookies; Mayer suggests on his blog that the Safari more this principle applies. The implementation in Firefox is something even smoother, because cookies of the sites that the visitor has previously visited, however, be allowed to pass. Nevertheless, Google Chrome blocks by default, no cookie, while in Internet Explorer depending on the settings of third party cookies that can partly be passed.

The new cookie implementation from Mozilla, following the imminent failure of the do-not-track standard. Although almost all browsers support it by default, with particular resistance from the advertising industry, and disagreement over the correct implementation ensure that the privacy option in the little practical proposes. Also legislation, including the controversial Dutch cookie act, the consumer net have little privacy protection on.

By a commonly used browser such as Firefox by default, third party cookies blocked, is the discussion around the do-not-track-standard may become obsolete. Nevertheless, there are sounding from the ad-industry has been criticism on the proposed blocking of third party cookies in Firefox.
