Perhaps you have set FF4 not to allow cookies so there are none?

You can see them yourself by going to Firefox/Edit/Tools -> Preferences/Options -> Privacy tab and click [Show Cookies] button. If you have any, they will display here. You can also remove them selectively or all at once. You should also be able to see them from your file manager wherever your OS stores your Firefox profile.

If you are seeing cookies from within FF but your AV is not, then you've just narrowed it down to your AV. If they aren't showing up in FF and you double check by poking around in your profile directory, and you still don't see any, that means you don't have any.

Also note when looking for the cookies in Preferences/Options the settings for cookie control are on that same Privacy tab.

The Privacy tab shows cookies but the Anti-Virus does not. If i clear all my cookies with that affect my passwords? Thanks Lou

Sorry I'm so late getting back to you.

If you had FF remember the passwords when it prompted you to, then no, it will not affect them. However, if the only way to store the password was via the particular website's "remember me" or similar feature, then yes, you will lose that saved password when you delete the cookies. You can delete them selectively if you like. Either from the FF cookie manager, or from your file manager, the cookie name should be self explanatory. They are just text files, so you can peek at them if you feel the need for more info.

Note, most websites don't have to have the cookie set for password retention. FF's built-in password manager should work just fine. (there are exceptions, like Hotmail for instance)
