This morning I tried to boot up firefox but it gave me a wierd popup window.I've had this thing before but I don't remember how I got rid of it.Well, the problem is that I choosed the wrong "profile" or user or wtf it is.And now I want to change back to my old one!
Please help me
In the "Start" menu select "Run" and enter:
This will start Firefox with the profile manager window, so you'll be able to switch back to your previous profile.
Thank you Varelse! That's exactly the answer I wanted
