D3 - Devise Design Develop

Here’s a Firefox extension that I can see as being another vital tool to web developers trying to get those pixel-perfect web 2.0 applications done faster and with less hassle. It’s called FireBug and does a lot of things that the popular Web Developer extension does such as highlighting and code views but this also give additional support for Javascript debugging, CSS and JS tweaking on the fly and Exploring a treeview of the DOM. One of the coolest features, however, is the ability to monitor network activity so you can see exactly what is taking your pages so long to load. With the increasing complexity of even the most basic websites, tools like this are going to be a vital resource to keep production time down.
