Here is a comprehensive Firefox Extension Development Tutorial. The tutorial covers the following topics:
- Development Overview
- Environment Setup
- Configuration Files
- Creating GUIs
- The Backend
- Preferences
- Localization
- Distribution
- Security
I think that virtually everyone who is a programmer either professionally or as an avocation, and who also is devoted to Firefox has considered creating a Firefox extension or add-on, whether seriously or not. Even if you haven’t yet I suggest bookmarking this extension development tutorial in case a great idea for one comes to you one day.
In addition to creating an extension that would solve an immediate problem of your own, there would be the additional benefit of being able to tell potential managers in interviews that you’ve actually developed Firefox extensions before!
