When the dialog box "Add certificate exception" comes up with the warning "You are about to override how Thunderbird identifies this site," which is the safe box to check?

I want to stay with Thunderbird's security system. Do I check "Confirm Security Exception" or "Cancel"?

Unfortunately, some sites do not maintain their certificates properly. So basically if you trust the site, you can confirm the exception. If it is an unknown site or you are not sure about it, then Cancel. Of course if you don't confirm the exception, you won't be able to see/use the site.
