Thank you very much for this information. Unfortunately, for me no such thing is available, my addon is self-distributed as mentioned:
I mean I can understand why they want to review public extensions available on AMO, but having to wait for an undetermined amount of time for addons that are self-distributed makes no sense whatsoever, especially in cases where you need to push critical updates fast, and time is of the essence. People using such addons probably already know what they are doing anyway, and it can make a huge (negative impact) on small organizations such as mine.
I am not going to raise any pitchforks here, been using Firefox for probably over 20 years, but if this is the way they are going to move forward then there should have been some kind of clear communication going on, a disclaimer.
