Kiosk mode is supposed to have only one window opened per Firefox instance as it's running in fullscreen and can't switch focus.

So there's no plan to fix it? If you have multiple monitors - running kiosk on one monitor and a normal browser on the other is a perfectly normal scenario ...

You may use fullscreen mode for it (F11 key). Kiosk mode is supposed to run as exclusive and only desktop app.

This is a valid bug.

I have the following command in a .desktop file:

firefox --kiosk --new-window  teams.microsoft.com

The purpose it serves is to double click on it and open the specific website as a Progressive Web App on its own window, without wasting space for address bar etc. The advantage is that it re-uses the already running Firefox profile, where I have many other normal windows open.

The bug here is that after this command, the behaviour of the already running firefox profile is altered: Ctrl-N does not open new window normally, but only in undecorated full-screen kiosk mode. There is no way to revert the behaviour without closing everything and restarting.

Yes, I understand you. OTOH kiosk mode is intended as single-window full screen only. What you use is actually a bug in Firefox Kiosk mode. For PWA you should use an extension (https://addons.mozilla.org/en-US/firefox/addon/pwas-for-firefox/ for instance) as native PWA support was removed from Firefox.
