Rated 2 out of 5 stars

This is what I thought I had been looking for years! At last! It promised to make Thunderbird with Lightning into a decent, fully functional PIM, a true competitor to all the others - but it just misses out.

Things don't always work as well as they do when you use the address book as a separate program - which is a real pity.

I hope Thunderbird developers really get behind this concept and develop a truly native implementation that addresses the few glitches - this would make Thunderbird a truly killer app!

This review is for a previous version of the add-on (1.2).
