Development techniques

Logging
Log messages to the console for diagnostic purposes.
Creating reusable modules
Structure your add-on in separate modules to make it easier to develop, debug, and maintain. Create reusable packages containing your modules, so other add-on developers can use them too.
Unit testing
Writing and running unit tests using the SDK's test framework.
Chrome authority
Get access to the Components object, enabling your add-on to load and use any XPCOM object.
Creating event targets
Enable the objects you define to emit their own events.
Listen for load and unload
Get notifications when your add-on is loaded or unloaded by Firefox, and pass arguments into your add-on from the command line.
Using third-party modules
Install and use additional modules which don't ship with the SDK itself.
Localization
Writing localizable code.
