I noticed that Firefox asks to auto-fill only one password/account data per domain.
But there are multiple websites that have different accounts for subdomains as well.
So it would be convenient to have a password save for seperate subdomains.
Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.
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.
(Note: a similar idea has been merged into this thread)
