The articles below include content about downloading and building Mozilla code. In addition, you'll find helpful articles about how the code works, how to build add-ons for Mozilla applications, and the like.
- About omni.ja (formerly omni.jar)
- Firefox and Thunderbird achieve performance improvements by moving many of their internal parts from being standalone files or sets of JAR files into just one JAR file called
omni.ja; this reduces the amount of I/O needed to load the application. Since Firefox 10 and Thunderbird 10, the file extension
.jais used because Windows System Restore does not back up files with the
.jarextension, but it does back up

- Command Line Options
- Command line options are used to specify various startup options for Mozilla applications.
- Debugging a project as large as Mozilla can be a daunting task. Fortunately, over the years, Mozilla developers have come up with not just technologies and features to help you debug code, but have devised tips and techniques that can help too. Also available are assorted tools that you can use when debugging.
