Firefox 17 causing X server crashes

[Eva Myers]

I have a problem with the new Firefox 17 on SL5 machines with ATI
Radeon X300 graphics cards using the fglrx driver.  The X server will
frequently crash when a user attempts to start Firefox, leaving the
computer with its screen black and unresponsive to mouse or keyboard
(the Xorg process just sits there eating CPU).  Does anyone know a fix
for this problem?
