Here are some things to try:
■
Choose Safari > Preferences and click the Bookmarks tab. Make sure that Include Address Book is checked. You can add the address book to the bookmarks bar, menu, and/or library (as a collection).
■
In your address book, check to see if any of your contacts have websites listed in the “home page” field. If no websites are listed, there are no home pages to include as bookmarks.
