I'd start with a little education.  Force them to go through a
tutorial before they're let loose, or make up a sign with instructions
and hang it on the wall beside the machine.

Sure.  Change the icon to run a wrapper shell script which checks
first to see if the binary's running.  The script would grep the
process table:

   #!/bin/sh
   #

   if [ "$(/bin/ps fax | /bin/grep '/usr/bin/mozilla-firefox')" ]; then
      exit 1
   else
      /usr/bin/mozilla-firefox &
      exit 0
   fi
