Rated 5 out of 5 stars

Just installed it for Thunderbird 3.1.10 under Ubuntu Maverick 10.10. At first I couldn't figure out how to access it; just right click on a folder and it is the last item on the list. I just migrated over from Windows, and had emails going back to 1997. Just created an address book with almost 4000 addresses. Wow, just great. Thanks!
