Not an error code I recognise, so it is probably an error code from your addon. I did not actually notice that addon in the official addons support site.

Is the addon even available for the Current Firefox 48 ?

If I have identified this correctly th esupport site appears to be 

http://www.listlabelship.com/support.php

maybe they can help you.
