Firebug integrates with Firefox to put a wealth of web development tools at your fingertips while you browse. You can edit, debug, and monitor CSS, HTML, and JavaScript live in any web page.
After you install Firebug you will see a gray 'Firebug' in the Firefox Navigation toolbar (along the top of the window). Click on the Bug to start. Firebug will open in the bottom of your web page.

Enabling Panels
To work on Javascript code or to study the network action on a site, you need to enable one or more Firebug panels. If you select the Console, Script, or Net panels, you will see the tab is grey and the panel says "disabled". Each panel tab has a small menu control for enabling the panel. All the panels can be enabled or disabled using the context menu (right click) on the Firebug status bar icon.Coming up for Air (or email...)
Once you have enabled one of the active-listener panels, Firebug will cause some overhead. Look at Firefox's toolbar: you will see that the Firebug icon is now orange, meaning 'on'. As you change tabs, Firebug will suspend if you have not opened Firebug on that page.for more information you guys could see the link:
