How do I switch to a different Mozilla user profile?

Question

When I went to open up a Mozilla window, a little box popped up and asked me if I wanted to use default or a new profile. Well I clicked default and it said I couldn't use it b/c it was in use so I had to click new. The default has all my bookmarks, how do I switch back? Where can you view these options? Thanks!

Answer 1

for windows go to start>run then run firefox.exe -P or firefox.exe -profilemanager

Answer 2

Check the Processes tab under Task Manager and look for any instances of Firefox and End Task. That should remove the default profile lock so you can use it again. If that doesn't work, then I'm not sure.
