User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:42.0) Gecko/20100101 Firefox/42.0 Build ID: 20151029151421 Steps to reproduce: If there are more than two emails addresses on a single Apple Contacts (Address Book) entry, Thunderbird will only be able to display the first two emails from the "Mac OS X Address Book" list. In the other words we need more "Additional Email" fields, right now it's limited to only one. Actual results: The 3rd and any more email addresses will not display, and not able to use in TB. Expected results: Display all the emails no matter the number of them.
