Two handy FireFox extensions

Just a quick plug for a couple of FireFox extensions I’ve been digging recently. Chris Pederick’s Web Developer toolbar / menu extension combines ideas from a whole bunch of other extensions and bookmarklets in to one extremely useful whole. The usual assortment of validation and element outlining options are present, but the really useful tools are “View Cookie Information” and “View Response Headers”. I’ve used separate extensions for these before but it’s handy to have them all in one package.
