Can the Firefox password manager store and manage passwords for multiple sub-domains, or for multiple URLs in the same domain? The default behavior of Firefox is that all requests for *.domain.com are treated as the same. I'd like to have Firefox do the following:

• Store and manage passwords separately for multiple sub-domains, e.g. mail.google.com and picasa.google.com

• Store and manage passwords separately for different URLs in the same domain, e.g. http://mail.google.com/a/company1.com and http://mail.google.com/a/company2.com
