Summary
Analyze keywords

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.

Ubuntu 24.04. Works perfectly thanks for your hard work!

It's a little finicky out of the box on Zorin OS, which defaults to flatpak Firefox. But I found I could switch to the snap version and have success installing the additional components necessary. I've also noticed I often need to launch PWAs twice, the first time they close immediately and the second launch they perform fine. I like being able to control whether the PWA uses it's own or a shared profile. I've found the shared profile useful for using Office365 apps like Word, Excel, Outlook, and Teams which I need for work, but isolated profiles are great most of the time.
