Yahoo! Mail added a new feature that populates your contact’s details page with information from Facebook. “To activate any Facebook-related feature, you first link your Facebook account by clicking on “Add to Facebook” in status section of Yahoo! Mail. After you sign in with Facebook, your Yahoo! Contacts now gets filled with information from Facebook to make it even more useful. Specifically, for any contact that uses Facebook, you’ll now see public details about them automatically added from Facebook. For e.g., you’ll see their Facebook photo and any information they’ve chosen to share publicly – like current location & work history. For contacts that you’re also connected with on Facebook, you get to see even more about them including their birthday, email address if you don’t have it, and even their most recent status message – right from their contact details page,” explains Yahoo!.
