I have an firefox extension with the name myjavascriptfile.js,As I am new to this addon concepts,just I want to debug this script.So I am using the following statements in this file like

function LOG(text)
{
    var consoleService = Components.classes["@mozilla.org/consoleservice;1"].getService(Components.interfaces.nsIConsoleService);
    consoleService.logStringMessage(text);
}

    {
      LOG("observe called ");
}

I know this observe is getting called but I dont know where to see my log message.can some one tell me Where it is printing?
Please help.

That text goes to the Error Console. You might need to go to about:config and change devtools.errorconsole.enabled preference to true – the Error Console was removed from the menus by default while ago (strangely enough, I could still see it even without this pref). I think that on OS X you can still open the Error Console via Tools / Web Developer menu, on Windows you have to click the Firefox button and choose Web Developer menu there. Alternatively, Command-Shift-J should do as well.
