I am using Firefox 75 on my Gnu/linux Kubuntu laptop. I want to be able to install PWA websites as web app on my system, something which is easy on Chromium and even GNOME Web.
I have found some workaround which suggests to add browser.ssb.enabled with value of true in about:config. I have done this and install option has come to the menu. But the app doens't show up anywhere in the system. I just can see the app after clicking on that option and if I close it, the app vanishes for ever.
Any idea?
