Firefox stable vs Firefox ESR super stable

[f23948]

i don't know what you mean:

Code:

sudo mv firefox-esr /opt

I mean my own:

Code:

sudo apt autoremove --purge firefox

Code:

sudo add-apt-repository ppa:mozillateam/ppa

Code:

sudo apt-get update

Code:

sudo apt install firefox-esr

Firefox regular stable has been uninstalled. Firefox ESR stable has been installed. Am I correct? I don't like to keep it both
