Hi MargoN2000, Who is your email provider? Since Firefox does not provide email service (unless you are a Mozilla employee), you would be better off looking for documentation on your provider's site. Here are some of the more common ones: * [http://support.google.com/mail/?hl=en Gmail Help] * [http://help.yahoo.com/l/us/yahoo/mail/ Yahoo! Mail Help] * [http://explore.live.com/hotmail-help-center Hotmail Help] Hopefully this helps!
