How do I get to my address book?

How to get the prompt for 'Add to address book' to appear on emails from new email accounts?

• There used to be a prompt beside the email address asking if you want to add the address to your address book if the email was not recognized by Yahoo mail. That has disappeared. How do I get that prompt back, or is there another way or easier way to add a new email address to the address book using a shortcut?

• Answer:

  It's gone forever, and you have Yahoo to thank for that. Obviously, they didn't consider it to be important, although everybody else did. So it's back to square one (for now)----click on "contacts"---click on "add contact"---enter the address and any info you want----click "save".
