Thunderbird address book

file extension .mab {=> wm : Mork adress book ? }

Is stored in the abook.mab and history.mab files in the profile directory.
You can also create additional address books that get saved in other .mab files
Copying files of that format into the directory won’t work ,
because only abook.mab and history.mab will be found automatically.
Others are known only, if created or imported within the thunderbird.

Format is the widely disliked Mork format, disowned even by its creator, for which few third-party developers wish to figure out how to do any kind of support.

==use Thunderbird’s import and export features to get data between this and other formats.==
