How to get a specific error for damaged Firefox extensions?

Background:

I am working on an extension for Firefox and obviously made a mistake somewhere. This is my first extension, so I won’t be surprised if the problem turns out to be something simple.

The problem is that I can't even get a decent bug from Firefox to track down the problem.

Problem

When I try to install my extension by dragging the XPI file onto the Awesome / Location panel, I get the error message "This add-on cannot be installed because it seems to be damaged." This is not a terribly useful mistake for those who are trying to develop and expand.

Does anyone know how to get a more detailed error message? Googling around I could not find anything myself.

Firefox has an error console under "Tools"> "Web Developer"> "Error Console" (ctrl + shift + j for me).

Open the error console, there will probably be a lot of warnings. Clean it all up and then try to do something, i.e. install the extension. The console will automatically update.
