New password.
Firefox doesn't ask if I want to save my new password in my Yahoo mail.
Yahoo mail recently made us change pw and now I have to erase the old one and type in my FULL pw before opening my mail. (every day) Listed in FF security, my Yahoo mail pw is not current.

You may wish to consider whether or not it is wise to store the Yahoo password on Firefox.
If you do decide to do so then you may need to use a bookmarklet or an extension to help you do that, after deleting the current password.
Also make sure to use a Master Password in Firefox to protect your stored passwords.
