test():

  ko.prefs.setBoolean("mytest", true);
}

Error: [ERROR] console-logger: ReferenceError: ko.prefs is not defined (2) in chrome://test/content/prefs/prefs.js:2

You have to get it from the parent window, eg:

var ko = parent.opener.ko || parent.opener.ko.windowManager.getMainWindow().ko;

Thanks a lot, Nathan! Hope you add this trick to your new Komodo modding documentation :smile:

Or you load the Komodo core via the script tag:

<script src="chrome://komodo/content/globals.js" type="application/x-javascript"/>

then you can use require to load sdk modules:

var prefs = require("ko/prefs");

Thanks, Todd. I think I will use this method instead of Nathan’s method.
