This add-on is perfect for running a web application in a separate browser window as if it were a native app (like a "PWA" for the desktop). On Linux, it's quite convenient to use this add-on with e.g. the Outlook web app instead of https://github.com/julian-alarcon/prospect-mail and the Microsoft Teams web app instead of the Linux client, which crashes a lot. With this add-on, there is no need to install an extra electron-based app that runs in its own little web browser (i.e. electron), when I can just run it in a separate window of my existing browser.

I was looking for something that worked like Chrome Apps for Firefox. This is even better! It works on any tab without configuration. One click and instant app window from any tab. Perfect!
