I'm making a firefox browser add-on, and I just got all of the code working fine, but it will only install in FireFox 16, and I want it to be compatible at least from 10+, has anyone dealt with this issue?

I have my package.json pointing to my install.rdf, and my install.rdf clearly states target applications. Is there any additional setup I need?

here is my package.json

{
    "name": "firefox-ext", 
    "license": "MPL 2.0", 
    "author": "", 
    "version": "0.1", 
    "fullName": "firefox-ext", 
    "id": "jid1-AMCw25iQJof53w", 
    "description": "a basic add-on"
}

and here is my install.rdf.

  </Description>
</RDF>

I'm using the CFX CLI Tools to make this, so everything has been built and tested with

cfx init, cfx run, and cfx xpi

I just can't figure out compatibility with anything other than 16.

Also, major bonus points if someone could explain the advantages of a rapid release cycle, because it really seems to have shot 3rd party Mozilla developers in the foot in terms of software compatibility.

Thanks,
