I have just upgraded to Extreme Security in the last 2 weeks. I now find that every time I close Firefox 3 all my cookies are deleted. I have spent a week or so eliminating everything else. Is there something in Extreme Security (eg Forcefield) that could be deleting the cookies? If so how do I fix it?

Operating System:Windows XP Pro
Software Version:8.0
Product Name:ZoneAlarm Extreme Security
