Essential Firefox Extensions For Webmasters

Mozilla Firefox is truly the best browser for web designers and developers. It’s Extensions system makes it possible to equip your browser with tools to make your life easier. But if you’re reading this, you probably already know that.

What extensions are the most useful for webmasters?

  • ColorZilla – Like having Photoshop’s Eyedropper tool in Firefox.
  • Lorem Ipsum – Generate Pseudo-Latin dummy text.
  • Firebug – “edit, debug, and monitor CSS, HTML, and JavaScript live in any web page.”
  • IE View – Open the current page in Internet Explorer.
  • MeasureIt – Drag a ruler across your browser’s viewport.
  • Web Developer Toolbar – One of my favorites, this extension adds dozens of useful options to your browser’s arsenal. You can disable JavaScript and CSS, resize your window to exact dimensions, and more. Here’s one of my favorite parts: Press Ctrl-Shift-F to toggle a “Element Inspector” tool. Forget the DOM Inspector, this is more useful.
  • YSlow – How fast is your website? How can you improve it? Requires Firebug.
