Allow password saving for pages in Firefox password manager
Currently, putting a website like https://foo.bar/login into Firefox's password manager will be trimmed to https://foo.bar. Occasionally, pages from the same domain or subdomain will have separate password fields. It would be useful to save passwords to subdomain by default, but allow manual creation of a login for a specific page that would take priority over the subdomain.
