A note about site passwords: If you use the Firefox Password Manager option, your saved passwords are not usually deleted when you clear your browser history of cookies and cache. However, to use Password Manager, you cannot also have the History setting Clear history when Firefox closes. You must instead use custom History settings (see below link).
