- /**
- * This module wraps the incompatible Gecko 1.9.0 (Firefox 3.0) and Gecko 1.9.1
- * (Firefox 3.5) JSON APIs, presenting the Gecko 1.9.1 API on both versions,
- * for extensions that support multiple versions of Gecko-based applications.
- *
- * Import this module into your extension to parse and stringify JSON in both
- * Firefox 3.0 and 3.5 (and other Gecko-based applications, like Thunderbird)
- * without checking the application's version each time.
- *
- * Note: don't import this into the global namespace! If you do, you'll hork
- * native application code that expects the Gecko 1.9.0 API. Instead, import it
- * into your own object like this:
- *
- * let MyExtension = {
- * JSON: null,
- * ...
- * };
- * Components.utils.import("chrome://myextension/modules/JSON.js", MyExtension);
- * // Now MyExtension.JSON is an object implementing the Gecko 1.9.1 JSON API.
- *
- * The Gecko 1.9.1 (Firefox 3.5) JSON API is documented in the article:
- * https://developer.mozilla.org/En/Using_JSON_in_Firefox
