Firebug 1.0, In depth
Latest Firebug 1.0 is finally available for public, while many of us was using the beta version since long time. I thought I knew most of Firebug usage until I saw Joe's presentation in the YUI Theater. I see it the developer tool not only for JavaScript programmers, but also for web2.0 designers, after or during web application development it's interesting to see it live on your browser make changes and see how it render. I enjoyed especially the profiler section, where you can detect any anomaly, make changes, test and so on until you find the most suitable configuration.
Unfortunately the IE edition is on its very early stages compared to what the extension do already with Firefox, while debugging JavaScript in IE a real mess especially if you have AJAX with iframes and so on ... just be ready to get lost! You can download Joe's presentation from YUI blog, 97MB MOV, or watch it embeded to this page.
Also about hacking pages using Firefox, John Resig showed in a presentation posted on his blog how to hack Digg using Firebug and jQuery. Interesting to see how you can use Firebug to explore web pages and run JavaScript locally on the page, then John make it as a Bookmarklet. The whole thing is a very small piece of code, that you cannot make it shorter with Greasmonkey.
Highly recommend you to get the latest Firebug 1.0 if you didn't already, watch the presentations above, and enjoy !.
