The .bashrc gets executed from bash, the command-line shell, when it is
used in interactive mode. Please, try running the command line below
-----------
firefox
-----------
from a terminal window (I assume thaht [1] the terminal is using bash as a
shell, [2] firefox isn't already running and [3] .bashrc contains correct
'export' lines).
It shoud run the browser and you should be able to verify that the
workaround works; if not so, something bad happened.

So, what can be done? Well, you simply have to customize your graphics
evnironment by putting the export lines in some startup file. Since I don't
personally use that workaround, I don't remember where I put it on the
target machine: let me know wether you've been able to solve and,  if not
so, I'll get back to the target machine (next week) and tell you more.

I hope my english is understandable :-)
