Rated 2 out of 5 stars

I was pleased with the UI at first sight. I then figured out that it created 370 new contacts in Thunderbird, most of them duplicates (up to 7x) and almost all with broken encoding and random characters in random fields. Shortly after, Thunderbird crashed. It also crashes when trying to use write-only mode.

This review is for a previous version of the add-on (2.0.11).
