Firebug: Web Applications made easy!

If you are in software industry and if you are a Web Developer, or involved in any of the Web Applications, then you must use a very useful tool called Firebug. It is an open-source debugger for HTML, JavaScript, and Ajax that works inside of Firefox. In fact, it is available as an add-on (one of the many which Firefox offers), and probably the most useful tool for debugging. Java Script is one of the widely used application language for the Web; so it becomes really handy to have this tool to modify, test, and debug Web applications.

Firebug was developed by Joe Hewitt. He was one of the original creators of Firefox. He now works as a programmer for Facebook. Firebug allows debugging, editing, and monitoring of any website’s Style Sheet, HTML, DOM Structure, and JavaScript, and provides other web development tools. The official site for firebug has the full info about it.

Here are some of the best features of Firebug.
·    DOM Inspector
·    Command Line Java Script Interpreter
·    Java Script Console
·    Logging Ajax requests (I have not used this feature)
·    Inspecting HTML and editing it.
·    Pin-pointing the error.

The power of Firebug added with the functionalities of the most popular browser makes it one of the best tools for analyzing Web Applications. If you do not want to use Firebug, you can easily disable it. Or instead of disabling firebug for all the pages, you can also specify particular sites for which you want it disabled, or specific sites for which you want to enable Firebug inspecting. The status display at the bottom right will immediately tell you if there are errors on the page or not. Also, it has these cool extensions to it which allows managing cookies and syntax highlighting (Rainbow). One of the extensions is YSlow which analyzes web pages and tells you why they’re slow based on the rules for high performance web sites!

This is one of the good articles I found which helped me a lot to understand how to use Firebug.

A small price to pay for this comes with the fact that it slows down the browser sometimes. But with the capabilities it offers, this is a small overhead! And since almost all the users of Firefox are on Firefox 3, this is where you get Firebug compatible for this.
