What am I doing wrong?

Answer 1

The answer is - the command "cfx xpi" from mozilla add-on sdk will overwrite install.rdf if you have it in project folder. So, to get things work properly - create xpi package, unpack it (unzip) - and you will find auto-generate install.rdf inside (!!!), substitute install.rdf with your own and re-pack xpi with zip command.
That's all, folks!
