Progressive Web Apps for Firefox wot Filip Štamcar

Important: Please make sure to update the native program to 2.14.1 from the GitHub repository (or your package manager) before Firefox 136 is released on 2025-03-04 to fix compatibility issues. If you still have problems after updating to 2.14.1, make sure that the native version mentioned in the extension settings (About the project) is also 2.14.1. If it's not, uninstall the native program from the system settings and try again. If everything is updated to 2.14.1 but you still have problems, please run "Patch profiles and runtime" from the extension settings.

Progressive Web Apps (PWAs) are web apps that use web APIs and features along with progressive enhancement strategy to bring a native app-like user experience to cross-platform web applications. Although Firefox supports many of Progressive Web App APIs, it does not support functionality to install them as a standalone system app with an app-like experience. This functionality is often also known as a Site Specific Browser (SSB).

This project creates a custom modified Firefox runtime to allow websites to be installed as standalone apps and provides a console tool and browser extension to install, manage and use them.
