New Thunderbird extension publishing via AMO

Hello,

Is it still possible to publish a new Thunderbird extension?
AFAIK, Thunderbird does not support WebExtensions, so if I need to publish a new Thunderbird extension on the store… How can I do that?

Thanks
Emmanuel

There should be no restrictions for extensions that support Thunderbird.

OK, maybe I have some problem in my XPI or manifest.
When I tried to upload my xpi (for private publishing, or distribution on my own (staging)) it was rejected for the reason it does not support WebExtension…

I have to check.
