ColorZilla for Firefox
ColorZilla is a little tool that sits in your status bar and offers an eyedropper, color picker, and rudimentary full-page zoom settings. It’s useful for quickly grabbing and comparing colors on a webpage. The full-page zoom settings resize the text and images, but backgrounds and other stylistic aspects are left the same.

Web Developer
The Web Developer extension is a must-have for web developers. It offers over a hundred different tools to help web developers get their work done, all from a convenient and well-organized context menu or toolbar, depending on your preference. Some particularly useful features include: live CSS and HTML editing; options to disable images, scripts, cookies, or a number of other things; view server response headers; a ruler showing the pixel coordinates of the cursor position and selected elements; various outline tools; quick access to a number of validation tools, including for non-public pages; and view generated source to see how the page has been modified by scripts.
