Similar to this question Why does removing Firefox install another browser? when I try to remove Firefox installed via apt, apt tries to install Chromium as an alternative as I have dependencies that require a browser to be installed.
I'm using Firefox flatpak from flathub and have set this to default in Gnome-settings and xdg:
$ xdg-settings get default-web-browser
org.mozilla.firefox.desktop
How do I set the Flatpak Firefox to satisfy the apt browser requirement?
