I've been looking for a long time for an add-on like this. Should be included by default in Thunderbird. Most other e-mail clients allow sending to several addresses by using a list of comma separated values. Now Thunderbird does it too, with the help of MRC Compose!
Works flawlessly. Many thanks to the developer.
