Facebook unexpectedly switched everyone’s default email address to the @facebook.com! If you go to your profile, you’ll see the @facebook.com email account listed!
Here’s how to switch back to your previews settings…
Go to your Timeline.
-Click update info, and then in your contact info, click edit.
-Switch all of the crossed out circle symbols to a full circle for each inbox you want visible on your profile.
-If you don’t want @facebook.com to show up, switch it from a full circle (Shown on Timeline) to crossed out (Hidden from Timeline).
It is now a good opportunity to check your privacy settings (make sure your inboxes are visible only to friends).
