Set Private/Igcognito Mode As Default In Firefox, IE8 and Chrome

All modern web browsers support what is called private browsing mode or incognito mode, where the browser leaves no trace of your browsing history behind in the computer.

Firefox have stated supporting private mode with the 3.1 beta version about which you can read in detail here.

Google Chrome likes to call this feature as Incognito mode and you can start a new incognito session by using the key combination Ctrl + Shift + N.

IE8 likes to call it InPrivate Browsing and you start a new session just like in Chrome.

Today’s post is for those paranoids who wish to always run their browsers in private mode making their web browsing untraceable at all time.
