Most impressive Rated 4 out of 5 stars
I'd give this extension a 10 but I haven't used it long enough yet to find any bugs. But so far it's great. It does just what I need and FAST, using templates for replies or for new messages. I've just switched to Thunderbird from Eudora on Mac because of Eudora crashes and so far I'm very happy.This review is for a previous version of the add-on (0.9.9.9).
