In FireFox's debugger, how do I break at the first line of JavaScript that an addon runs?

I need to break at the entry-point, but I don't know what the entry-point is.

Solution

  • The entry-point is determined by manifest.json. For example, the background scripts section:

    {
  "manifest_version": 2,
  "name": "My Add-on",
  "version": "1.0",
  "description": "A description of my add-on.",
  "permissions": ["activeTab", "scripting"],
  "background": {
    "scripts": ["main.js"]
  },
  "browser_action": {
    "default_popup": "popup.html",
    "default_icon": {
      "48": "icons/icon-48.png",
      "96": "icons/icon-96.png"
    }
  }
}
