Mozilla Thunderbird email application stores its contacts in Abook.mab and Abook.sqlite files.

Older Thunderbird application stores address book contacts in MORK format. And the contacts are saved in a file named as abook.mab.

Whereas in new version of Thunderbird email application contacts are saved as sqlite database files and are stored in abook.sqlite file. When Thunderbird saves a contact in abook.sqlite file then for safe contacts writing it creates few temporary files as abook.sqlite-shm and abook.sqlite-wal.

To read the contacts from abook.mab file and abook.sqlite file you can take help of 4n6 MBOX Converter application.

In old Thumderbird editon, adding new address books to Thunderbird that are saved in other .mab files can be done, but you must use the filenames specified; otherwise, extra ones won’t be discovered.

The Mork format, which was developed by Mozilla, is not very popular; as few third-party developers want to support it, you can use 4n6 MBOX Converter tools to migrate data between this and other popular contacts formats.
