How to remove firefox

Question

I tried :

sudo snap remove firefox

snap "firefox" is not installed

sudo apt-get purge firefox

Package 'firefox' is not installed, so not removed

when I click at "Applications/Internet" I still see firefox.

Answer 1

I don't have enough points to ask in a commentary, but my guess is this:

If firefox can be uninstalled using apt or snap, maybe was not installed with either of those; maybe is a flatpack or an appimage. Or directly compiled from source. Can my guess be a possibility?

cheers

Answer 2

using the command:

flatpak list --app>

check whether it is flatpak app?

if yes, use command below to remove:

flatpak uninstall --delete-data App-ID
