I have upgraded to the latest firefox 3.6, i have restarted my system and I played an online game on "www.darkorbit.com".They have also upgraded their game client but I don`t think these is the problem since is an online flash game and i also had the same error in the past on ie7 + digicooltv plug-in(online live tv streaming).At that time i solved the crashes by removing the plug-in and stop using ie all together.I am using windows xp on a pc with an athlon 4000 am2 x2 on m2a-vm asus mb with 4gb ram, an ati 2600 hd pro and a 500gb hdd.I also am using an bitdefender antivirus and firewall that is up to date.
