That is very odd: the error seems to be generated by firefox needing to access X functionalities (which is normal), but those export commands should be sufficient to make it work (if you have a running X session on the hosts).

The only tips I can give to you is to replace the export line like this (you should only need one):

#export DISPLAY=:0.0

export DISPLAY=:0

or try to explicitly set the display on each command:

su user1 -c 'DISPLAY=:0 firefox -no-remote -CreateProfile firefox18'
