## Description

PassFF is a Firefox add-on that connects the unix password manager `pass` (passwordstore.org) to your browser. Once the companion native host is installed, PassFF can read your pass store, present matching entries in the browser, and optionally autofill and auto-submit login forms for a seamless sign-in experience.

This extension requires that you already use `pass` and have it configured on your system. Follow the project homepage instructions to install the native host application. PassFF is designed for existing `pass` users and is open source — see the project README and host installation guide on Codeberg for full setup and security details.
