Project Description

Firebug is free and open source. It is a powerful Firefox extension that helps you to view HTML and CSS code, adjust your styles and see the results immediately, understand your page layouts, debug and log JavaScript, manage cookies, analyze page load times, examine error messages, and more.

Firebug is a web development tool that facilitates the debugging, editing, and monitoring of any website’s CSS, HTML, DOM, XHR, and JavaScript; it also provides other web development tools. Firebug’s JavaScript panel can log errors, profile function calls, and enables the developer to run arbitrary JavaScript. Its net panel can monitor URLs that the browser requests, such as external CSS, JavaScript, and image files. The net panel can display both request headers and response headers for each page asset; it can also estimate the time each asset took to load. In addition to debugging web pages, Firebug is a useful tool for web security testing and web page performance analysis.

Firebug integrates with Firefox to put a wealth of web development tools at your fingertips while you browse. You can edit, debug, and monitor CSS, HTML, and JavaScript live in any web page. 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. It also gives you fine-grained control over which websites you want to enable it for.

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. 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. 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.

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. When things go wrong, Firebug lets you know immediately and gives you detailed and useful information about errors in JavaScript, CSS, and XML. Execute JavaScript on the fly. The command line is one of the oldest tools in the programming toolbox. Firebug gives you a good old’ fashioned command line for JavaScript complete with very modern amenities.

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.

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.

Firebug allows you to view and manage cookies in your browser. You can deny cookies for specific sites, filter cookies, create new and delete existing cookies. You can also break into the debugger when specific cookie changes its value and see the line of script that caused the change.
