Firefox Profile Manager not opening (V20.0.1)

I'm trying to open the Profile Manager in order to create a 'developers' profile. I was originally following this blog's instructions using the Run command.

http://blog.mozilla.org/addons/2009/01/28/how-to-develop-a-firefox-extension/

The problem is that it's just opening up a new Firefox window, and nothing else. I then went to get more updated documentation, here:

https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles?esab=a&as=aaq

And alas the same results. Here are the commands I have tried:


firefox -p firefox -P firefox -profilemanager firefox -ProfileManager

"C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -p "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -P "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -profilemanager "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -ProfileManager


They all return the same result, which is just opening a new Firefox window.

This happens when Firefox isn't completely closed and you still see a firefox.exe process or plugin-container process in the Task Manager.
