Must Have Firefox plugin for the Web Developer Types

Do you build or work on web sites? Do you have the FireBug extension for Firefox yet?  If not, why not?

Holy cow, this thing is awesome and the 1.0 beta is looking very yummy. Highly recommended.

Don’t/can’t use Firefox for some reason? Have a glance at FireBug Lite then.

I’ll concede I’m a bit late on this one… I’d tried an early version once and dropped it rather quickly. But now? I’m awe-struck at how useful it is.
