Firebug integrates with Firefox to put a wealth of development tools at your fingertips while you browse. You can edit, debug, and monitor CSS, HTML, and Javascript live in any web page.

It's an absolute must-have if you're into writing up your own Javascripts and you've found yourself going nuts trying to figure out why they won't work. This extension will help you quickly and easily zero in on Javascript errors and will tell you exactly what went wrong (as opposed to the vague, snippy Javascript error messages issued by Internet Explorer, e.g., 'Object expected').

- Just the way you like it
Firebug is always just a keystroke away, but it never gets in your way. You can open Firebug in a separate window, or as a bar at the bottom of your browser. Firebug also gives you fine-grained control over which websites you want to enable it for.

- Inspect and edit HTML
Firebug makes it simple to find HTML elements buried deep in the page. Once you've found what you're looking for, Firebug gives you a wealth of information, and lets you edit the HTML live.

- Tweak CSS to perfection
Firebug's CSS tabs tell you everything you need to know about the styles in your web pages, and if you don't like what it's telling you, you can make changes and see them take effect instantly.

- Visualize CSS metrics
When your CSS boxes aren't lining up correctly it can be difficult to understand why. Let Firebug be your eyes and it will measure and illustrate all the offsets, margins, borders, padding, and sizes for you.

- Monitor network activity
Your pages are taking a long time to load, but why? Did you go crazy and write too much Javascript? Did you forget to compress your images? Are your ad partner's servers taking a siesta? Firebug breaks it all down for you file-by-file.

- Debug and profile Javascript
Firebug includes a powerful Javascript debugger that lets you pause execution at any time and have look at the state of the world. If your code is a little sluggish, use the Javascript profiler to measure performance and find bottlenecks fast.

- Quickly find errors
When things go wrong, Firebug lets you know immediately and gives you detailed and useful information about errors in Javascript, CSS, and XML.

- Explore the DOM
The Document Object Model is a great big hierarchy of objects and functions just waiting to be tickled by Javascript. Firebug helps you find DOM objects quickly and then edit them on the fly.

- Execute Javascript on the fly
The command line is one of the oldest tools in the programming toolbox. Firebug gives you a good ol' fashioned command line for Javascript complete with very modern amenities.

- Logging for Javascript
Having a fancy Javascript debugger is great, but sometimes the fastest way to find bugs is just to dump as much information to the console as you can. Firebug gives you a set of powerful logging functions that help you get answers fast.

After installation, Firebug will appear as a green check mark in the bottom right corner of Firefox (assuming the page you're currently viewing contains no script errors).
Firebug will notify you when the current page contains Javascript errors by displaying a red circled 'X' in the bottom right corner of Firefox followed by the number of errors.
- To view the error messages, click the number of errors notification to open the Firebug console. The error messages will be listed in the console along with which web document contains the errors, which lines of code in that document are producing the errors, and the respective line numbers.
Many thanks to Jamey Boje for designing the Firebug logo.

Firebug is an extension for Firefox, but what happens when you need to test your pages in Internet Explorer, Opera, and Safari? If you are using console.log() to write to Firebug's console, you'll wind up with Javascript errors in these other browsers, and that's no fun.
The solution is Firebug Lite, a Javascript file you can insert into your pages to simulate the Firebug console in browsers that are not named "Firefox".

If you don't want to install Firebug Lite, but you just want to avoid those annoying Javascript errors, grab firebugx.js here and just copy and paste it into your web page code.
