Most web developers would agree that, whilst designing, design for FF/Opera and fix for IE. Therefore FF is used as the primary testing browser. Thanks to the ability to integrate extensions into FF, your web developing can become a lot easier with the following list of extensions.

1. IE View - https://addons.mozilla.org/en-US/firefox/addon/35
   Lets you, with 2 clicks, open a page in IE. Useful for testing.
2. Web Developer - https://addons.mozilla.org/en-US/firefox/addon/60
   No developer should be without this.
3. HTML Validator - https://addons.mozilla.org/en-US/firefox/addon/249
   Validates HTML as you work.

There are a lot more out there. If anyone has any to recommend, please leave a comment.
