I have a firefox profile with certain proxy settings set. When I type firefox.exe in the run dialog Box in windows it opens up the default profile. I have a firefox shortcut specified with the command line args -P "profilename". I want this to be used as it will force the custom profile. Is there an environment variable that i can set for this?

firefox -P "profile_name" is the correct format.

Easier is use a desktop shortcut to the Firefox executable appended with [space]-P "profile_name"

You can set the default profile to use in the Profile Manager to be used when no profile is specified and otherwise use desktop shortcuts with a profile specified (-P "profile").
There is also a "Don't ask at startup" check box in the PM window.
