Firefox crashes on Intrepid

[matthias]

I was running firefox and using facebook uploading photos. Then it crashed. I tried running firefox from the terminal, and when it crashed, it gave me this:

The program '<unknown>' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 7738 error_code 8 request_code 145 minor_code 4)
  (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.)
INTERNAL ERROR on Browser End: Pipe closed during read? State may be corrupt
System error?:: Resource temporarily unavailable
Segmentation fault

Anyone has any ideas on what happened?
