A few reasons, among which is that the addon needs an account on the Test Pilot site to work. It&#x27;s not a standalone add-on, so we didn&#x27;t want to distribute it that way. And we may eventually even migrate away from using an AMO compatible add-on.<p>That said, we are also contemplating AMO hosting as an interim step.

So, lots of things converging on this one thing :&#x2F;
