Firefox's upcoming web apps feature won't work the same as in other browsers - but it's better than nothing https://www.omgubuntu.co.uk/2025/03/firefox-nightly-supports-web-apps-taskbar-tabs
@omgubuntu adding progressive web app support, while not really focusing on the "app" part seems counter-intuitive. It feels like that would undermine the goals and primary benefits of PWA. But, yeah better than nothing.
