About this extension

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.

Important: To fix a critical security vulnerability, make sure to update (at least the native program) to v2.12.0 as soon as possible.

You can check out the installation and usage instructions on our documentation website. You can also check out the project's source code and more information on the GitHub repository.

Note: I will appreciate it if you read and participate in a GitHub discussion to suggest how to make this project more user-friendly and which features would you like the most. You can also read and participate in a GitHub discussion about the documentation website.

Developer comments

You will need to install additional software for this extension to function, you will be prompted to install it after installing the extension.

Warning: Extension cannot detect the native program when using sandboxed Firefox (when using Flatpak on Linux). This is a limitation of the Native Messaging API and cannot be fixed. Check #76 for more details and workarounds.
