About this extension
This extension is an independently adapted Firefox-compatible version of the Billfish screenshot and visual material management tool.

The original Billfish software and Chrome extension are created and maintained by the Billfish development team. However, the team has not released an official Firefox extension. In order to continue using the same workflow on Firefox, this version was re-packaged and made compatible with Firefox’s WebExtension (Manifest V2) requirements.

Key features:
- Capture full-page and visible-area screenshots
- Annotate, crop, and manage captured materials
- Provides similar UI behavior to the original Chrome version
- Runs entirely locally without collecting or transmitting user data

This project is a compatibility adaptation only. No modifications were made to functional logic beyond what was required to meet Firefox’s extension policies.

All copyrights, trademarks, and original assets belong to their respective owners.

This Firefox extension is an unofficial adaptation and is not affiliated with, endorsed by, or associated with the official Billfish development team. All original rights, trademarks, branding, and assets referenced or used by this extension belong to their respective owners. This package was created solely to restore compatibility for Firefox users due to the absence of an official release. No user data is collected, stored, or transmitted.

Licensing Note:
This Firefox adaptation does not modify or distribute the original Billfish source code.
