Firebug for Firefox 3

Firebug is a very handy extension for web developers. You can edit, debug, and monitor CSS, HTML, and JavaScript live in any web page. Currently I am using Firefox 3 beta which is not supported by the current build but is by the development build. Firebug is really an outcome for AJAX development since you can't see the code normally that is generated by your AJAX stuff. Firebug enables you to debug your javascript. Since the website is down for the moment I made the xpi for version 1.2 beta 5 available for download or intallation here.
