Bugzilla

Thanks everyone for testing. 

To recap, it is Thunderbird-macOS AB initialization/interaction that causes the problem. Settings possibilities are:
* Unchecking "Local Address Books" in Thunderbird preferences, BUT that only affects the use non-ldap address books for compose compose and does not prevent Thunderbird-macOS AB initialization
* **Changing Contacts privacy settings in macOS preferences (listed below) prevents Thunderbird-macOS AB initialization and is an effective workaround**
* Changing ldap_2.servers.osx.dirType from 3 to -3, this "disables" the Mac OS X Address Book in Thunderbird, preventing it from displaying - I am uncertain if this also prevents Thunderbird-macOS AB initialization (perhaps someone could test it)

macOS preferences workaround:
1. open macOS System preferences
2. type "privacy"
3. click privacy settings
4. click contacts
5. at the bottom click the lock and provide your password
6. uncheck the box for thunderbird
7. restart thunderbird
