The feedback given look relevant to me (from the article): "Your version was rejected because of the following problems: 1) Extending the prototype of native objects like Object, Array and String is not allowed because it can cause compatibility problems with other add-ons or the browser itself. (data/toolbar-button-panel.html line 40 et al.) 2) You are using an outdated version of the Add-ons SDK, which we no longer accept. Please use the latest stable version of the SDK: https://developer.mozilla.org/Add-ons/SDK https://developer.mozilla.org/Add-ons/SDK 3) Use of console.log() in submitted version. Please fix them and submit again. Thank you."
