Do you remember how frustrating it can be trying to track down that missing semicolon or misplaced closing bracket? You probably already know this, but sometimes the difference between minutes and hours lost can be the quality of tools available to you. According to John J. Barton, if you’re programming dynamic web pages with Javascript and are using Firefox as your browser, then you definitely want Firebug in your toolbox.
Firebug is an open source add-on that integrates with Firefox to put a wealth of web development tools at your fingertips while you browse. Using Firebug, you can edit, debug, and monitor CSS, HTML, and JavaScript live in any web page.
In this short tutorial, Barton explains how to use Firebug’s JavaScript profiler to measure the performance of a web page. With performance information available, he then illustrates how to use Firebug to identify performance bottlenecks. To conclude the tutorial, Barton uses Firebug to demonstrate the performance improvements gained from the changes made using Firebug.
