Firefox Extensions Useful for Web Developers

Firefox isn't only for web browsing, but can also be a useful tool for developers. If you are a web developer, you can install and take advantage of Firefox wide array of developer-friendly extensions. The following is a list of some Firefox extensions that I enjoy using:

• View Source Chart Creates a Colorful Chart of a Webpage's Rendered Source Code
• Dummy Lipsum Generate "Lorem Ipsum" dummy text
• Domain Details Find the whois information, IP Address and other information, including Search Engine stats and server information, on the site you are visiting.
• JSView View the source code of external stylesheets and javascripts.
• HTML Validator Adds HTML validation to the View Page Source of the browser. The validation is done by Tidy by W3C.
• Firebug Unified debugger for HTML, CSS and Javascript. The only one and the best.
  

There are still more Firefox extensions for web developers from here.
