I am merely reporting a symptom of an extension that is being promoted within the browser. I don't know who needs to do what to make this work and I never implied anyone should do anything for it. I haven't found anything prior to this which discouraged me from using it ("not being required" is not the same as "it does not and will not work")
Given that you yourself mentioned that this extension never worked, and that it will not work until it is fixed by the extension developers, why is it being promoted within the popular extensions? The presence on the list suggests it is supported and working correctly. If it is not, I think it is better to remove it from that list.
