Mozilla Firefox’s most wanted add-on FireBug is now available in google chrome.
Firebug Lite is not a substitute for Firebug, or Chrome Developer Tools. It is a tool to be used in conjunction with these tools. Firebug Lite provides the rich visual representation we are used to see in Firebug when it comes to HTML elements, DOM elements, and Box Model shading. It provides also some cool features like inspecting HTML elemements with your mouse, and live editing CSS properties. Firebug Lite 1.3.0 beta for Google Chrome is basically the same you’ll see when using the bookmarlet.
