Two handy FireFox extensions
5th March 2004
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.
The second is something which really should be built in to every browser: Clear HTTP Auth, which lets you log out of HTTP authenticated sites without having to close all your browser windows.
