Activate JavaScript console for Firefox

Mex — Tue, 10 Dec 2013 14:16:00 +0000

For whatever reason, the JavaScript console is not working for Magento by default. So if you try to output messages using console.log, nothing will happen. To change that, open js\varien\js.js and uncomment the following code:

if (!("console" in window) || !("firebug" in console))
{
    var names = ["log", "debug", "info", "warn", "error", "assert", "dir", "dirxml",
    "group", "groupEnd", "time", "timeEnd", "count", "trace", "profile", "profileEnd"];

    window.console = {};
    for (var i = 0; i < names.length; ++i)
        window.console[names[i]] = function() {}
}

What is “var Translator” and can it be removed?

If you take a look at your Magento stores code, you might see the following JavaScript code:

var Translator = new Translate({...});

You might ask yourself, if its safe to remove that and what that code does. The code is responsible for translating your forms. Its safe to remove it, if you setup your store with only one language. If thats the case, you can safely remove the above code.
To rmove the code, open app/design/frontend/default/theme/template/page/html/head.php, and remove the following code:

helper('core/js')->getTranslatorScript() ?>
