But no one can defeat Firefox because of its performance, feature and most striking is the add-on.

1. Firebug



Firebug integrates with Firefox to put a wealth of development tools at your fingertips while you browse. You can edit, debug, and monitor CSS, HTML, and JavaScript live in any web page.

2. IE Tab V2

Just like the classic IE Tab, this updated version of IE Tab allows you to use IE to display web pages in a tab within Firefox. This updated version includes support for Firefox 3.6 and will continue to be updated with new features and enhancements.

3. Font Finder

FontFinder is created for designers, developers and typographers. It allows a user to analyze the font information of any element on a page, copy any piece(s) of that information to the clipboard, and perform inline replacements to test new layouts.

4. ColorZilla 

With ColorZilla you can get a color reading from any point in your browser, quickly adjust this color and paste it into another program. You can Zoom the page you are viewing and measure distances between any two points on the page. The built-in palette browser allows choosing colors from pre-defined color sets and saving the most used colors in custom palettes. DOM spying features allow getting various information about DOM elements quickly and easily. The powerful CSS gradient generator allows quick and easy creation of beautiful gradients.

5. YSlow

YSlow analyzes web pages and suggests ways to improve their performance based on a set of rules for high performance web pages. YSlow is a Firefox add-on integrated with the Firebug web development tool. YSlow grades web page based on one of three predefined ruleset or a user-defined ruleset.

6. Php Developer toolbar

8. Web Developer
 

The Web Developer toolbar is a must-have for web developers (arguably better than Firebug).
One of the features is showing all CSS / JavaScript (inline and external!) of the current page. Each slice can be collapsed, so that you don't have to scroll through a big wall of text before finding the desired line of code. Unfortunately, the NoScript extension disables this feature.


9. Illuminations for Developers for Firebug

A set of tools to help you develop web applications by investing Firebug with the knowledge of the JS framework you are working with. Supports ExtJS and Sencha Touch, with beta-level support for Dojo Toolkit, SproutCore, qooxdoo, YUI, Google Closure Library, and jQuery UI.

10. Scroll Up Folder
