[K12OSN] Firefox crashes

This page also crashes FF running on disklessworkstation.com's LTSP Term 

Running the mozilla debugger options produces this at the point of crash:

The program 'Gecko' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
  (Details: serial 145503 error_code 11 request_code 53 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

Program exited with code 01.

I don't understand - would this problem really be remedied by having 
more RAM? My i810 boxes that exhibited the same crash all had more than 
64MB memory (One had 384). On the other end of this is the 1225 
terminal, which has 16MB videoram (specified in lts.conf) and 128MB total.

I can't imagine that this crash is pervasive; no one would be using LTSP 
if it were. I'm wondering what it is about my specific location (And 
those whom are also affected) that is causing this to occur so often and
