Firebug was a Firefox extension, which allowed the debugging, editing, and monitoring of any website's CSS, HTML, DOM, JavaScript, network traffic and cookies. You should just use this tag in case the question is directly related to Firebug itself and not a website you are debugging with Firebug.
Firebug was a Firefox extension that allowed the debugging, editing, and monitoring of any website's css, html, dom, and javascript. It also had a JavaScript console for logging errors and executing JavaScript as well as a network monitor, which measured the amount of time in milliseconds it took to execute scripts and load images on the page. And it included a way to check and edit the cookies a website sets. Furthermore it had many extensions, which enhanced its functionality.
It became a must have aid tool for developers and testers around the world, but has now been discontinued by its developers.
Firebug is free and open source, licensed under the BSD license.
Relation to Firebug Lite
