Why is my Firefox boot extension causing errors?

Question

Why is my Firefox boot extension causing errors?

I am new to developing Firefox extensions. So I experimented a bit. I'm currently trying to create a boot extension with no more than minimal requirements: only install.rdf and bootstrap.js. At the moment, this extension should not actually do anything. I only want to install it without any problems. Functionality can be added later.

The install.rdf and bootstrap.js settings were packaged in a .zip file with 7zip, then the file extension was changed to .xpi. The installation was done through AddOn Manager and it seems to work fine in my Firefox 42.0 (Firefox gives me a success message).

But if I look at the error console after installation, it shows a few warnings / errors:
