My Firefox version: 26. I've installed Python 2.7. OS: Windows Vista, SDK: 1.14

Solution

  • I suggest getting the latest version of the SDK (addon-sdk-1.15.zip) from the Mozilla Developer Hub :: Add-ons for Firefox web page. Also make sure to read an follow the instructions in the README file that comes with it (if you haven't already).

    One pertinent thing it says is:

    If you get an error when running cfx or have any other problems getting started, see the "Troubleshooting" guide at: https://addons.mozilla.org/en-US/developers/docs/sdk/latest/dev-guide/tutorials/troubleshooting.html
