I haven't had time to really mess with Firefox much more lately, but I noticed something else that might help you debug ... Just now I had a Firefox session running, and it had done the ecab reload thing when it started like normal, but that was over and done, and the session has been running for quite awhile. Windows Live Messenger was running, and I doubleclicked on the icon in the system tray, to bring up the Messenger program with its friend list. Just as the Messenger window popped up, the eCabs reload thing happened again. So this time it was triggered by Windows Live Messenger, and I think I have noticed this happen before a time or two. I will copy the Event Viewer info below. Running Windows Live Messenger version 2009 (Build 14.0.8089.726).
