Mozilla does not want to support PWAs in Firefox, yet MDN has a PWA manifest and can be installed in Chromium.

Firefox supports PWAs, at least on mobile.

Are they PWAs tho, or just shortcuts?

They open in a window separate from the browser and don't display the browser toolbar, so not just shortcuts.
