Many sites do not get automatically added to the list of saved passwords - possibly a security precaution on the part of the sites in question, to prevent hacking of usernames and passwords. Since my memory is not what it used to be (and never was!), it would be helpful to be able to manually add websites, usernames, and passwords to the saved PW list. Then, they could be securely looked up, protected by the Firefox Master Password, when they can't be remembered and don't automatically fill in on a web site. This would be vastly preferable to continually needing to re-register to a web site when a password is forgotten.
