Let's check to see if these are problems in the extension.

Undoubtedly that can be done; I mentioned randomly only few of them. On the last thirty add-ons I had installed for occasional use, at least five of them were affected by the present issue. Testing all the add-ons available in the Mozilla Firefox collection would not seem at first sight to be indicated as a relevant test procedure.

Check the browser console (ctrl-shift-j) when you open the popup. If an error similar to the following is reported as a result:

> TypeError: backgroundPage is null

Then it's a duplicate of bug 1329304.

Filter output "TypeError: backgroundPage is null" doesn't produce any target.
