Thunderbird extension console logging - firefox-addon

Question

I have the following code in my bootstrapped Thunderbird add-on main.js file:
exports.main = function() {
console.log("abc");
};
When I run this code in FireFox in Add-on Builder, I get this message displayed in FireFox Error Console:
info: vladp: abc
However, when I run my extension in Thunderbird nothing is displayed. I have set up the development enviroment as described here: https://developer.mozilla.org/en-US/docs/Setting_up_extension_development_environment
How do I make it work in Thunderbird Error Console? Or is there any other way to log some debug information, apart from "dump()"?
UPDATE 1
As suggested by speedball2001, I've changed my code to:
exports.main = function() {
var Application = Components.classes["#mozilla.org/steel/application;1"].getService(Components.interfaces.steelIApplication);
Application.console.log('Bam!');
};
However, when I run Thunderbird, I get the following error in error console:
Timestamp: 2013.05.22. 16:39:07
Error: myfirstext: An exception occurred.
ReferenceError: Components is not defined

How do I fix it?

Answer 1

Thunderbird provides an Application interface that, among other things, helps with logging:
var {Cc, Ci} = require("chrome");
var Application = Cc["#mozilla.org/steel/application;1"]
.getService(Ci.steelIApplication);
Application.console.log('Bam!');
