I would like to have 2 different profiles to start Firefox. I suppose I can do that through the command line, but I failed to find the command line options in the support web site. I work on Windows XP...

Thank you.

Hi Fcousin. 

* If Firefox is open, close it completely by choosing "File -> Exit".
 * Go to the Windows Start Menu (bottom left button) and then select 'Run'. On Windows 7 or Vista, press "windows key+R" 
   * Enter (without quotation marks) "firefox -P" (i.e. firefox space hyphen P ) then click OK
