Chosen solution

The easiest way is just copy the whole profile.

Help menu > troubleshooting information

Close Thunderbird

In windows explorer select all and copy. paste everything onto a thumb or other read/write portable media (not CD or DVD)

on the new Machine repeat the troubleshooting and close steps to get the current profile folder

This time paste everything from the portable media into the profile replacing what is there

Open Thunderbird, your done mail contacts add-ons everything
