I am not much of a programmer, and have been using JPM to create an addon. When firefox updated a couple of weeks ago the addon stopped working.
I have tried getting the addon validated for non-public use, and have fixed everything except a trivial missing instal rdf (whatever that might be), but I am completely blocked by the message:
Your add-on failed validation with 1 error.Duplicate add-on ID found
But what is an addon ID? Where do I find it? What is it a duplicate of?
Thanks
