c:\Program Files\Minefield>firefox -Profilemanager --no-remote

* Create a new profile, like "minefield" and use it every time you want to use minefield.

* '''NOTE:''' If at any point you run Firefox2 and then you try to open Minfield(codename for Firefox3), you will just end up running another window of Firefox2 (I will explain later how to run both at the same time). ''It happens vice versa too.''
