Have you tried calling it with the same profile multiple times? I've been running into "Firefox is already running" a lot while trying to use it to integrate web apps with the OS ("site specific browser"). Also the WM-Class would never be set according to the command line parameters on the second call, but you probably don't care about that.

For my use case I don't want to call it w/ the same profile multiple times. Once I have the FF process, I'll work with tabs/windows via the remote protocol.
