Firefox NewUser

Script to run a Firefox instance with a dynamically created temporary user exclusively in Wayland environments. This project is specifically designed to work on Gentoo Linux; its functionality on other distributions is not guaranteed. The user and all their data are automatically deleted when the browser is closed, ensuring a clean and isolated session.

Features

• Total isolation: Creates a dedicated system user (firefox_newuser) for the session.
• Automatic cleanup: Deletes the user, their group, and their /home directory after execution.
• File synchronization: Allows moving files downloaded or created during the session to a persistent directory before deletion.
• Optimized for Wayland: Uses native session management for modern environments.
• Sound support: Automatically bridges PipeWire/PulseAudio sockets and authentication cookies to ensure audio works out of the box.

Requirements

• Python >= 3.10
• root privileges (the script will request them via su if run as a normal user).
• Firefox installed.
