Rated 3 out of 5 stars
I second "My_Nick..." I use Thunderbird for both my personal and business email. I make the "from wrong identity" mistake only when composing new emails. It never seems to happen when replying, maybe because I don't use local folders. So this feature would be much more useful to me when composing new messages. Thanks!This review is for a previous version of the add-on (1.3.1).
