session - Run different Firefox profiles concurrently?

Purpose

Because of my somewhat excessive use of tabs—which often contain PDFs'—I use 64-bit builds of Firefox. It has now gotten to a point where I want to use different profiles; one for my research the other for my day-to-day stuff.

Attempt

1. Created a new profile called: Research, by running Firefox with the -P CLI arg.


2. Quit Firefox


3. Created two shortcuts following the official documentation; linked to:
   
   
   
   • [path to firefox]\firefox.exe -no-remote -P "Research"
   
   
   • [path to firefox]\firefox.exe -no-remote -P "default"
   
   
   
   


4. Opened each shortcut

Result

Only the fast profile clicked loaded; opening the second shortcut just opens a new Window in the previous profile. Same happens if I open them with inverse order.

Troubleshooting

I tried linking the shortcuts to different Firefox binaries (i.e.: HTguard, Waterfox, Cyberfox) to no avail.

How do I get multiple profiles to work side-by-side; on Windows 8?
