The most interesting part of firebug 1.0 Beta (the single most essential Firefox extension for web developers) is that this essential tool is free. However each version has always been twice as smarter and feature rich from its earlier version, this version has definitely something extra that can enhance your developing project to its next level.
My favorite enhancements of this version are as below;
It enable you to undock into its own window—multi-monitor users! The DOM inspector now offers full in-place editing of your document structure more than the attribute values.
You can visualize CSS metrics and tweak CSS to perfection, the new features includes a powerful JavaScript debugger that lets you pause execution at any time. You can also monitor network activities.
You may find few more enhancements if you look on it, Get firebug and fall in love with it.
