crx-to-xpi

A simple tool that can help you port WebExtensions to Firefox easily.

Dependencies

• node
• npm (or yarn, whatever)

Usage

npm install -g crx-to-xpi
crx-to-xpi your-addon.crx

TODO

• Implement a better path processing method to support non-Unix-like environment.
• Give some warnings when the extension uses an WebExtension API that hasn't been supported by Firefox.
• Allowing the source code of the extension to be used as input.

How does it work?

This project helps you declare gecko support in manifest.json, and then zip up the source code into .xpi format.
