FireBug screenshotFirebug merges with Firefox to put a rich set of web development tools at your fingertips while you are browsing. You can debug, edit, and monitor HTML, CSS, and JavaScript live in any web page

Always at your service
Firebug is always just a press of a key away, but it never stays in your way. You can start Firebug in an independent window, or like a bar at the bottom of your web browser. Firebug also offers you fine-grained control over the websites you want to enable it for.

Edit and inspect HTML
Firebug makes it very simple to discover HTML elements hidden deep in the page. Once you have found what you were searching for, Firebug offers you a rich set of data, and lets you edit the HTML.

Tweak CSS to excellence
Firebug's CSS tabs informs you about the styles in your web pages, and if you are not satisfied, you can make adjustments and see them take effect directly.

Visualize CSS metrics
When your CSS boxes are not lined up right it can be hard to understand why. Let Firebug illustrate and measure all the padding, offsets, borders, margins, and sizes for you.

Oversee network activity
Your pages are taking a long time to load? Did you go insane and write too much JavaScript? Did you forget to shrink your pictures? Firebug breaks it all down for you file by file.

Debug and profile JavaScript
Firebug bundles a strong JavaScript debugger that lets you pause the process at any time and have look at the condition of the world. If your code is a slow-moving, use the JavaScript profiler to measure accomplishments and find bottlenecks very fast.

Find errors quickly
When things don't work, Firebug lets you know right away and offers you detailed and useful data about errors in CSS, JavaScript, and XML.

Explore the DOM
The Document Object Model is a large ranking of objects and functions just waiting to be activated by JavaScript. Find DOM objects fast and then edit them.

Execute JavaScript on the fly
The command line is one of the most aged options in the programming toolbox. Firebug offers you a command line for JavaScript full with very modern comforts.

Logging for JavaScript
Having a JavaScript debugger is great, but every now and then the quickest method to discover bugs is just to dump as much data to the console as you can. Firebug offers you a set of strong logging features that help you get answers quick..

Just the way you like it
Using Firebug grants you a lot of possibilities for web development.

Search and you shall find
Sometimes you know what you are looking for, but you can't see it in the panel. Using the fast search box in Firebug's toolbar you can search in Firebug's panels and see the results as you type.
