When you are a web developer and you like working in Firefox, then without a doubt you would have come across some or other mention of Firebug, the web development Firefox plugin that almost everyone who is anyone prefers to use when working on the web.
And while Firebug certainly is an almost indispensable tool, another web development add-on plugin that you really should give a go is Chris Pederick’s excellect Web Developer add-on that essentially provides almost all of the editing and overview information and abilities that Firebug offers but at the same time offers you just that much more overall information, making it a tool more than just a little worthy of sitting in your browser system.
Go on, have a look at it – I promise that you won’t be disappointed! :)
