Web Developer for Firefox
By Mitch “The Developa” Keeper
When you talk about awesome tools for Firefox to make your web development job just that much easier you can’t overlook the Web Developer toolbar extension. The best thing about this freeware download is that it mixes two great things into a handy tool to keep close at hand (Firefox and the Web Developer tools).
Once installed the addon will add a menu and a toolbar with various web developer tools. You can mess around with CSS, forums, resize the window, view the source and more. For a total rundown it might be best to check out the official site for every single feature because there are just too many to name right here, right now.

Web Developer Pro: The king of the mountain when it comes to Firefox/web dev tools.
Web Developer Con: Kind of bulky toolbar, but can always be hidden away.

It has all the tools you would ever want right there in one simple toolbar and it will not cost you a penny to use.

You can always make it less bulky by hiding the text.
