A must-have for web developers Rated 5 out of 5 stars

I've been using Firebig for years now. It is not a technical tool but also a learning tool. While you work on web, you learn and re-learn how your page works.

If you are learning web technologies like HTML, JavaScript or DOM install firebug and give it a try. You'll fall in love with it.

This review is for a previous version of the add-on (1.9.2.1-signed).
