1 year ago Thank you for showing interest in the project! :-) Progress is slow, as the currently provided APIs do not allow me to cover all the cases - I was able to get the extension to work in idealistic conditions, but it was already failing in scenarios where the message would not be successfully sent due e.g. to missing OpenPGP key. Anyhow, the related Bugzilla thread is available at:
https://bugzilla.mozilla.org/show_bug.cgi?id=724834
where it seems that the repository for the addon you mentioned ceased to exist, at some point.
Hello. I see you're on the path to implement a button "Send and Archive". Thank you! I enjoyed this extension, which is now gone: https://web.archive.org/web/20181007003701/https://addons.thunderbird.net/en-US/thunderbird/addon/send-and-archive/ May be able to get the old source code from user squib: https://addons.thunderbird.net/en-US/thunderbird/user/squib/
