How to import VCF cards into Mozilla Thunderbird

It seems odd that a major email application can't import the standard contact information file (.vcf) natively.  It's sad but true.

According to this support reply:

vCard or .vcf
Some address book programs use a vCard format, which cannot be imported directly by Thunderbird. You can import both vCard and .vcf using the third-party Thunderbird extension 'MoreFunctionsForAddressBook'.

• download to desktop or 'downloads' folder on computer.
• In Thunderbird. 'Tools' > 'Add-ons' to open 'Add-ons manager' in a new tab
• click on the daisy wheel icon and select 'Install Addon from file
• locate the .xpi file you downloaded
• click on Open to install in Thunderbird

Save the vcard / .vcf attachment to eg: desktop
In Thunderbird:

• open 'Address Book'
• select the address book you want it to go to
• 'Tools' > 'morefunctionforAddressBook' > 'Action for contacts' > 'Import vCard/vcf'
• locate the saved vcard/.vcf file and click on 'Open'

Download the .xpi file form that website address and follow the installation instructions, then you need to restart Thunderbird.

NOTE: You need to save VCF cards to file and import them, this won't work natively from the email itself!!!
