Import your Mac OS X Address Book into Thunderbird

Finally I found a relatively painless way to import the Mac OS X Address Book into Thunderbird (note this is a one off import, not a dynamic link).

So,

1. In Apple’s Address book, select the addresses you’d like to export in the list
2. Select File -> Export vCard…

and save the .vcf file

3. Download morecols
4. Launch Thunderbird and select Tools -> Import and select the morecols .xpi file
5. You’ll need to quit and relaunch Thunderbird
6. In Thunderbird, open Window -> Address Book
7. From the Tools menu, select Actions for contacts -> Import vCard/vcf
8. Select the vcf file you exported from Apple’s Address Book
