Firebug is a tool for Firefox that helps web developers debug their creations.

As web development moved beyond just HTML markup, debugging tools became necessary in order to debug and unit test this complex code. Firebug was among the earliest tools that attempted to deliver this type of platform. It is a Firefox extension that works on Mac as well as Windows and let developers interact with content as their users would while also providing debug and other information.

All of the data provided by Firebug is collected in real-time. It works with web files stored locally, served over a LAN and of course served via the Internet. It also does not have to be your content that you debug. If a particular webpage is given you trouble, you can debug it and determine if there is something on your end to be done.

Modern webpages generally comprise much more than just HTML. Firebug is able to debug and analyze HTML as well as XML, CSS, JavaScript, Adobe Flash and even images. It features a console as well as a DOM analyzer. It also has a Net tab through which you can see the requests being made to your site and the responses the client is receiving. This can be very helpful in determining the particular page or script that is causing the bottleneck or other issue.

Firebug was an amazing tool that changed the way we developed on the Web and really changed the Internet itself in some ways. Nevertheless, Firebug is now a dinosaur and no longer needed because everything that it offers is now included within the Firefox browser via the Developer Tools. But no one should forget that the Developer Tools we use today are a direct result of Firebug development.
