Although Firefox for Android has support for PWA websites in general,I see that it doesn't detect all pwa websites and creates a simple shortcut instead! For example go to mytuner-radio.com and try to install it as a Pwa, it just creates a shortcut! If you try this on other browsers like Vivaldi for Android, it installs it as an app, without the need to open the whole browser alongside all the tabs,every time you tap on its icon ! Please fix this and make all sites that support pwa detectable !
