What sets Firefox apart from all other browsers is ‘Extensions’. Extensions give additional functionalities and features to the browser. The Mozilla community is highly active and you have over thousands extensions to choose from. But the question is how to build an extension.

What many people don’t realize is that they’re so easy to create and implement. Anyone with a little knowledge of JavaScript and XML can easily build a Firefox extension. If you really want to make an extension, the e-book ‘Build Your Own Firefox Extension’ would be a great reference guide.
