About PWAsForFirefox
PWAsForFirefox is a tool for installing, managing, and using Progressive Web Apps in Mozilla Firefox. Firefox supports many PWA APIs but does not provide a way to install sites as standalone system apps, so this project supplies a modified Firefox runtime plus a command-line tool and browser extension to create isolated app-like installations with their own profiles. Setup involves installing the browser extension and following the in-browser installation instructions; a user guide and help section are available for detailed usage and troubleshooting.
