I've recently switched to Firefox and I feel like it's overall a better experience – I just really miss the convenience of installing Progressive Web Applications as a standalone apps, or creating shortcuts from existing websites.
The benefit of this is that you can open them as a separate window, keeping the viewport size and hiding the URL bar.
Is there any viable alternative to this in Firefox?
On Android Firefox has been able to install PWAs for a while, but not exactly as Chrome does (probably a restriction set by Google), they won't show up on the app list but only in your desktop.
I use Smart Launcher and after installing PWA there's an option to add it to app list. What is your launcher?
