The privacy mode which is available on some of the web browsers is often called as porn mode or secret mode. There are quite a few names given to this. The latest version of the Apple Safari browser already has this mode and it works well on Apple OS.

It is now the turn of Internet Explorer to offer this facility to the Windows operating system users. The browser will offer the privacy mode so that information regarding the websites surfed on the browser is not avaiable.

Two new patents have been registered by Microsoft related to this feature, they go by the name - "Cleartracks" and the other by "Inprivate".

Mozilla Firefox which is one of the most widely used browsers are in the process of developing this feature.

The IE8 version by Microsoft is due to be released by december or early 2009.
