Try vcard; I think it is more inclusive.

While there are often alternative approaches and solutions "export" should mean just that. Otherwise it should be called "Export, but not everything," Export, Everything," "Export, toss of the coin." I've worked for software development companies and it woould shock users to know how often backup and restore do not work as expected or intended. Thank you, David, for you alternative solutions. This entire problem arose because of a glitch with the LDAP Address Book feature introduce in Thunderbird a while back. One of those updates convered my non-LDAP Address book to an LDAP. Last week when I was editing my Address Book I notice some double entries. I deleted them. I then remembered I needed to call a friend, but their contact was missing from my Google Contacts. Those double entries in my Thunderbird Address book was an original contact and one synced from my Google Contacts. Not realizing the difference I deleted the Google synced contact from Thunderbird, that also delete it from my Google Contacts. Once I realized what was happening I undeleted those deleted Google Contact from Trash in my Google account. I then deleted the "converted during an update" Address Book from Thunderbird and created a new non-LDAP Address Book. And now we are at the export part of this conundrum. At no time ever did I use or create an LDAP Address Book in Thunderbird. So I am assuming a past update is responsible for converting my Address Book to a LPAD Address Book. I provided all of this extended explination for those who may have experienced the same problem I had.

Thank you for the feedback. You make a good point.
