logStringMessage function inside Firefox extension

Question

I was developing a small extension for Firefox. I wanted to log messages while a part of my extension is executing. CODE:

var aConsoleService = Components.classes["@mozilla.org/consoleservice;1"].getService (Components.interfaces.nsIConsoleService);
aConsoleService.logStringMessage("created"); 

Here "created" is message. But I am unable to see this message inside browser console. Am I missing something? I searched for it and got to know that you have to enable devtools.errorconsole.enabled inside about:config. I did that too. Please help me out.

Are you sure you're opening the browser console? Ctrl + Shift + J?

var {utils:Cu, interfaces:Ci} = Components;
Components.classes["@mozilla.org/consoleservice;1"].getService(Components.interfaces.nsIConsoleService);
consoleService.logStringMessage(text); 

also can try this:

var {utils:Cu, interfaces:Ci} = Components;
Cu.import('resource://gre/modules/Services.jsm');
Services.console.logStringMessage(text);

can also try this

var {utils:Cu, interfaces:Ci} = Components;
Cu.import('resource://gre/modules/Services.jsm');
Services.appShell.hiddenDOMWindow.console.log('blah');

if you're using addon sdk then instead of var {utils:Cu, interfaces:Ci} = Components; you have to do var {Cu, Ci} = require('chrome');
