Rated 3 out of 5 stars
This is a great product. I keep my thunderbird profile directories shared between Windows and Linux dual boot. If I use the Thunderbird in Windows, it disabled Lightning and after reinstall it works fine. And, when I get back to Linux, I again have to reinstall Lightning to make it work again. Needless steps as other extensions work fine in dual boot and shared directory. I would rate 5 star, if this inconvenience did not exist.
