Hi,
Maybe you could publish this at https://developer.thunderbird.net/add-ons/about-add-ons so that also other addon developers can get aware of this.
It is still a draft and was heavily modified in the last two days. We will send this information to all add-on developers (who are registered on ATN) this Friday. It will be added to DTN as soon as the related API for bootstrap extensions is done. John -- users@sogo.nu https://inverse.ca/sogo/lists
