Running executable using UniversalXPConnect
Hi I am using following javascript to run windows program but I get error message ->typeerror:netscape.security.privilegemanager is undefined. I am running firefox version 31. Is this outdated in latest versions of firefox ? If yes, can you please tell me the alternatives ?
function runApp() {
var ua = navigator.userAgent.toLowerCase();
if (ua.indexOf("msie") != -1) {
MyObject = new ActiveXObject("WScript.Shell")
MyObject.Run(path);
} else {
netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
var exe = window.Components.classes['@mozilla.org/file/local;1'].createInstance(Components.interfaces.nsILocalFile);
exe.initWithPath(path);
var run = window.Components.classes['@mozilla.org/process/util;1'].createInstance(Components.interfaces.nsIProcess);
run.init(exe);
var parameters = ["/c start winword.exe"];
run.run(false, parameters, parameters.length);
}
} catch (ex) {
alert(ex.toString());
}

Support for UniversalXPConnect has been removed quite some time ago and you can no longer use this method to run privileged code. You would need an extension to run a program.
There are extensions that you can look at.
- External Application Buttons 2: https://addons.mozilla.org/firefox/addon/external-application-button/
- PrefBar: https://addons.mozilla.org/firefox/addon/prefbar/
What do I need to make the following code work? Do I need any adds on for this ?? [Firefox version 31]
//Components.utils.import("resource://gre/modules/FileUtils.jsm");
//var env = Components.classes["@mozilla.org/process/environment;1"]
// .getService(Components.interfaces.nsIEnvironment);
//var shell = new FileUtils.File(env.get("COMSPEC"));
//var args = ["/c", "ping stackoverflow.org"];
//var process = Components.classes["@mozilla.org/process/util;1"]
// .createInstance(Components.interfaces.nsIProcess);
//process.init(shell);
//process.runAsync(args, args.length);

You need to run such code from within an extension to have the proper chrome privileges.
