John Resig blogs about the new Firebug release:
The Script panel (the JavaScript debugger), the Net panel (network monitoring), and Console panel have all seen considerable updates. They're all much more performant and have a huge number of bug fixes.
Firebug changes the way you develop for the web. You won't be able to go back to alert() and background-color: red after you spend some time with it.
