State of the tools for write addon for thunderbird

I am very new in developement of addons, but i wrote a addon for firefox and it was very simple and interesting using jpm.

now, I am interested in write one addon for thunderbird and my question is if I can use the JPM for this task. In other case what type of API, SDK or tool, we can use for create a addon for thunderbird and finally if in future jpm would be supported in thunderbird.

I searched a lot in MDN and i found a lot information, like “bootstraped extension”, “XUL overlay”, “restartless”, Addon SDK(“CFX” and “JPM”), but I am very confused, ¿which of these tecnologies can I use in thunderbird?

XUL Overlay and Bootstrapped extensions should work fine with Thunderbird. The SDK and JPM probably won’t work as well, or at all, since most APIs were designed for Firefox.
