Works in General Rated 4 out of 5 stars

This mostly works for me. However you may run into a problem if you agree to changing the identity on the send and the new identity has a replyTo field. You will either get no replyTo if the previous identity had no replyTo or the replyTo of the previous identity if it was filled in. Other fields such as the organization field work fine. It is not clear why this should be the case as I looked at the code and it appears to correctly assign the new identity. Hopefully someone with a more in depth knowledge of the peculiarities of Thunderbird's identity manager may be able to find a tweak for the code.
