how to show the path to an application for use by another program

[jeffinhedon]

Can you help please?
I am running a program called XARPM PLUS
This prog allows me access to a BBS in order to download bulletins etc
It has a function that will also allow compressed files to be resolved in the default web browser
My question is
How to show the path to the browser so that the prog will go to the web browser in order to show the resolved image
Where is the default browser located in the ubuntu file path
I guess it must be something like
usr/bin/firefox
or something like that
Just cant seem to find the correct path
Any advise will be very much appreciated
Cheers
