Firefox wayland on mir-kiosk

Hi,

I am trying to build a firefox wayland package that will run mir-kiosk. I am trying to follow this tutorial https://ubuntu.com/tutorials/wayland-kiosk#4-test-your-application-supports-wayland.

But I am now stuck please see the errors in this thread.

`miral-app -kiosk -terminal ‘/snap/firefox/current/firefox’ will start firefox inside mir-kiosk window.

It is not normally possible to run a snapped executable outside of the snap context. The tutorial suggests running the unsnapped, .deb install. I.e.

miral-app -kiosk -terminal firefox
