On Unstable (installed in 2018) I see:

toncho/~ 19 cat /usr/bin/firefox
#!/bin/sh

FIREFOX="$(command -v firefox)"
[ -x "$FIREFOX.real" ] && exec "$FIREFOX.real" "$@"

exec firefox-esr "$@"

toncho/~ 19 ls -lh /usr/bin/firefox.real
lrwxrwxrwx 1 root root 22 Mar 25 02:47 /usr/bin/firefox.real ->
../lib/firefox/firefox

toncho/~ 19 file /usr/lib/firefox/firefox
/usr//lib/firefox/firefox: ELF 64-bit LSB pie executable

toncho/~ 19 ls -lh /usr/bin/firefox-esr
lrwxrwxrwx 1 root root 30 Mar 24 18:43 /usr/bin/firefox-esr ->
../lib/firefox-esr/firefox-esr

toncho/~ 19 file /usr/lib/firefox-esr/firefox-esr
/usr/lib/firefox-esr/firefox-esr: ELF 64-bit LSB pie executable

toncho/~ 19  dpkg-divert --list firefox\*
diversion of /usr/bin/firefox to /usr/bin/firefox.real by firefox-esr
