Someone sends me an e-mail and I do not have their e-mail in my Thunderbird address book. Is there a way to enter their information into my address book without having to retype it all into my address book. In other e-mail programs that I have used, all I needed to do was click on the message and then click on a drop-down menu item that would simply copy all of the contact information into a new address book entry. Is it possible to do that in Thunderbird?
