- close all instances of firefox
- Start -> Run -> firefox.exe -ProfileManager
- create 5 or so profiles, I named them p1 - p5

- Start -> Run -> firefox.exe -P p1 -no-remote.
Each profile is totally distinct (history, cookies, etc...), only issue there does not seem to be an easy way to tell which profile you currently have open
