I am authorized to use my grandson's e0mail, my son- in - law's e-mail, my daughters e-mail and when I try to sign in it says Invalid account...What do I have to do to use these on Firefox?

Firefox doesn't do email, it's a web browser.

If you are using Firefox to access your mail, you are using "web-mail". You need to seek support from your service provider or a forum for that service.

If your problem is with Mozilla Thunderbird, see this forum for support. http://www.mozillamessaging.com/en-US/support/
