I had this problem on few different XP machines: Firefox crash over and over. When you select the 'restart' option at the crashed message screen it will reopen only to crash again. All the PCs are Windows XP SP2 and they all have a copy of eBlaster 6.0.3084. Surprisingly an upgrade fixes the problem... Installing eBlaster 6.0.3102 (and the required boot) make the problem go away... Nothing on eBlaster's site indicate they did anything to fix the problem but hey, if it's fixing it who am I to complain!
