“Firebug Lite is a subset of Firebug that can be used in IE, Opera, and Safari. The previous version provided console.log functionality. In Firebug Lite 1.2, Azer added the ability to inspect DOM elements, track XHRs, and navigate HTML, CSS, and JavaScript. You can embed it in your pages and enable debugging. I prefer creating a Firebug Lite bookmarklet that I can launch on any web page. Instructions and more information are available on the main Firebug Lite page.” source...
