Installing firefox-devedition and remove both firefox and firefox-esr

Hello everyone.

I am trying to replace firefox and firefox-esr on my kali installation with firefox-devedition.
I managed to install firefox-devedition as i already know how to from debian installs.
But i cannot remove both firefox AND firefox-esr. When i try them individually, the other gets installed. If i try both, i get the dependencies error (for kali-desktop-core).
Anyway to tell the system firefox-devedition is installed and should be used for dependiencies check? or am i missing something?

I am using kali rolling (fully updated) with gnome on a Thinkpad T480 if it helps in any way.

TIA for any help.
Cheers!

They are considered core components for kali, and you simply don’t remove them - may I ask why you actually want to?

As a dev said “firefox-esr allows us to set it so that it does not make outside connections when it starts up, and we have a policy of no outgoing connections by default in kali”
