What does this mean: 'Duplicate add-on ID found'

Add-ons Add-on Support
#1

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

Duplicate add-on ID found -> I am the owner of the duplicate

That message can appear for various reasons.
Either the add-on ID is being used by another add-on or the add-on with that ID has been deleted, which causes the ID to get blocked in order to prevent malicious takeover.

What is the add-on ID and what is your AMO account?

Thanks for the reply!

I do not think that I have an AMO account because this is not intended to be a publicly available add on. It is just something that a few of us use on our computers, and so I click that box marked: ‘Do not list my add-on on this site’ during validation.

Secondly, I have no idea what is meant by ‘add-on ID’. Is this the xpi file name generated by JPM? I really, really do not know. :frowning:

You can find the add-on ID in the install.rdf file inside the XPI file.

Ah, which is essentially what the jpm tool calls ‘name’. So my problem is probably that it is called ‘my-addon’… I should have used another name, but at the time I did not realize that validation would happen.

Thank you, I will try with a new name.

OK, all sorted, thanks Andreas :slight_smile:
