Add-ons written using JPM

Hi, I have trouble with one of my add-on which is written using JPM tool - it works perfectly on the development version of Firefox (40.0a2) but doesn’t work on the current version of the Firefox (38.0).

What is the problem - JPM generates own bootstrap.js file and all functionality should be inside index.js but on the current Firefox 38.0 is code in index.js not executed…

Should I wrote my own bootstrap.js file and forgot JPM or should I wait on new Firefox version?

My add-on is here: https://github.com/stop-it/firefox-addon

Regards and thanks for help!

What is your package.json saying main is? Mine has:
“main”: “index.js”,

Have you checked the Browser Console for any errors? Is the problem only happening on 38, or all versions?
