A lot of what is in this book can be learned by using Firebug to deconstruct other people’s web sites, I find it very educational to see how others are coding their web sites, and Firebug is great for that. It is so easy to use that I have been unaware of advanced features even after years of using it.
The section on extensions was also helpful as it introduced me to “Firecookie” and “Firefinder” which I have not used before. Firefind appears to be really useful for finding elements that match a particular CSS selector on a web page.
It didn’t take me very long to read Firebug 1.5: Editing, Debugging, and Monitoring Web Pages as I was already familiar with Firebug, I skimmed over quite a bit of it. But the sections that covered features I did not know about were great and I feel like I learned a lot that will help me be a better developer.
I read Firebug 1.5: Editing, Debugging, and Monitoring Web Pages by Chandan Luthra and Deepak Mittal using Safari Books Online.
