Using workers in JavaScript code modules Redirect 1

You can do so by using ChromeWorker instead of the standard Worker object. It works exactly like a standard Worker, except that it has access to js-ctypes via a global ctypes object available in the global scope of the worker

Obsolete since Gecko 8.0 (Firefox 8.0 / Thunderbird 8.0 / SeaMonkey 2.5)
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

Note: As of Gecko 8.0, the nsIWorkerFactory interface has been removed

 

Starting in Gecko 2.0 (Firefox 4 / Thunderbird 3.3 / SeaMonkey 2.1), you can use workers in JavaScript code modules (JSMs). This lets you run code in a separate thread from your JSM. To create a ChromeWorker for this purpose, you need to use the nsIWorkerFactory interface:

var workerFactory = Components.classes["@mozilla.org/threads/workerfactory;1"]
                              .createInstance(Components.interfaces.nsIWorkerFactory);

var worker = workerFactory.newChromeWorker("script_url.js");

This will create a new chrome worker that will immediately begin to run the script at the specified URL (in this case, "script_url.js").  For example,   "script_url.js" can be "chrome://extension_name/content/script.js".
