importing from Windows to Firefox on linux

[Les]

Hi, everyone,
I figured out the business of opening thunderbird on the windows machine
and importing the mail folders then exporting them to the transfer disk,
and reimporting them on Linux (It was a pain importing one folder at a
time, first creating the folder, then importing the file into it, but I
did it.)
Now I can't get the address book to import.  It is a CSV list.  I
checked it out and it appears correct.  Here is the header and one line:
First Name,Last Name,Middle Name,Name,Nickname,E-mail Address,Home
Street,Home City,Home Postal Code,Home State,Home Country/Region,Home
Phone,Home Fax,Mobile Phone,Personal Web Page,Business Street,Business
City,Business Postal Code,Business State,Business
Country/Region,Business Web Page,Business Phone,Business
Fax,Pager,Company,Job Title,Department,Office Location,Notes
A,Smith,,A. Smith,,AJSmith(at)somemail.com,,,,,,,,,,,,,,,,,,,,,,,

This looks good.  When I import the file, it recognizes it as a CSV
file, and imports it into "Personal", but when I check my address book
it is empty.

There are no error messages, no problems that I can detect, just the
data is absorbed into some mysterious bitbucket without accomplishing
the desired goal.

Any ideas?

Regards,
Les H
