Basically, you need to install enough of the gtk libraries to get 
Firefox working.  I don't know about the "best" way, but this should work:

   sudo apt-get install apt-rdepends
   apt-rdepends firefox | less

Start installing stuff from that list until it works.

Alternately, install libgtk2.0-0; you definitely need that library, and 
apt-get may pull in everything else you need when you install it.
