While firefox is open it will not open a link sent by a windows process that is outside of the firefox process. When I try this I recieve an error message stating 'firefox is already running but is not responding'

I have searched this message, and all results I have seen seem to indicate the browser must be closed due to firefox locking then profile when opening'. This is not an acceptable solution for me as I have 100+ tabs open.

And some applications I try to do this from obscure the url they are launching (I assume by a WinExec style API call). When this happens, I dot not know the url to maually enter, or have one to copy and paste.

Make sure that you do not start Firefox with the -no-remote switch or have set the environment variable MOZ_NO_REMOTE=1 (Control Panel > System > Advanced > Environment variables).
