Just a quick summary here at the end for anyone looking for an immediate answer:

This is not a bug; the documentation is just incomplete / unclear. If firefox is running already, you need to use slightly different commands from when it is not. Most of the docs assume you are not already running firefox.

To create a profile when firefox is *not* already running, use "firefox -ProfileManager &".
To create a profile when firefox is *already* running, use "firefox -ProfileManager -a blackmagic &".

To start firefox with a profile when firefox is *not* already running, use "firefox -P <profile name> &".
To start firefox with a profile when firefox is already running, use "firefox -no-remote -P <profile name> &".

Example:
I already have firefox running, showing this webpage. I want to create a new profile, so I open a terminal and enter firefox -ProfileManager -a blackmagic and create a profile called luser. I then run it by entering firefox -no-remote -P luser at the terminal. (I also created a launcher on my taskbar to do this without opening a terminal window)
