Rated 5 out of 5 stars
a really nice and usefull Add-on.
Unfortunately it doesn't work anymore with Thunderbird 52.1.1.
Maybe you could adjust this Add-On?
i would be really glad
I stopped maintainig this AddOn, because in current Thunderbird Versions the "Reply" Button has a Dropdown, that shows all emailadresses that Thunderbird finds in this email. So you are able to answer to the adress of your choice. Thats not exactly, what this AddOn did, but nearly (and more).
