Fantastic Web Developer Add-on for Firefox

May 13th, 2008

Web Developer Toolbar

Hey Guys! Found an awesome new Firefox extension!

I am actually quite excited about this. Recommended by a good friend - the Firefox ‘Web Developer’ toolbar add-on is one of the best designers aid I’ve come across. For a long time I’ve used the Tiny HTML validator which is a neat piece of kit, although can sometimes, I find, be over critical.

To cut to the chase - Web Developer is an add-on that can be found here. You install it, restart Firefox and bask in it’s power. Ok - it’s only a tool. As well as built in HTML, CSS and Javascript validation - you’ll find a plethora of tools including:

  • the ability to turn off and control java, javascript, cookies, CSS, page colours, images and more.
  • display different page information - eg. specific abbreviations, anchors, classes, images etc.
  • highlight page sections - eg. divs, frames, tables, headers etc.
  • Resize the window to specific resolutions to see how your site will render in different monitor sizes.
  • Plenty more if you hunt around

I seriously recommend this to any developer or designer. It’s a great tool not just for building your own sites, but for assessing and reverse-engineering other sites. When the old ‘how did they do that?’ questions arises - the Web Developer toolbar will help to outline and highlight specific areas of the front-end display and the code to help understand websites better.

You can download Web Developer from the Firefox site at https://addons.mozilla.org/en-US/firefox/addon/60.
