Thanks, that's even more fucked up.
What's even even more fucked up is that the package still installs an executable to /usr/bin/firefox, but it's just a wrapper script that launches the Snap application... and also replaces your desktop shortcuts, application launcher shortcuts, and favourites with its own Reforged Edition file if you're running GNOME, Unity, MATE, or KDE Plasma.
Excerpt from /usr/bin/firefox Canonical Edition(TM)

exec /snap/bin/firefox "$@"
I'd classify that as malware.
