Firefox addons

[denise]

I found Server Switcher while on my quarterly extensions trawl tonight, and I thought about the various extensions/add-ons I use regularly for development -- FireBug, Live HTTP Headers, ColorZilla, Web Developer, etc -- and figured: it might be a good idea to collect lists of "recommended" developer addons for those who use Firefox.

So: what are the add-ons that you couldn't work without?

Downtime

The Dreamhack machine will be down for ~10m or so at 4AM GMT tonight for Slicehost maintenance. They claim that active state will be saved, but it's a good idea to save anything you're working on beforehand.
