I'm updating the software on an older Acer netbook at the request of a customer. He was getting the message about the installed version of Firefox no longer being supported. Laptop is running Zorin OS (Linux).
I updated the system using "apt update" and "apt-distupgrade" as you normally would on a Debian based system. Started Firefox again. Still on an older version, but the version screen mentions Flatpak. So looks like Firefox is installed as a Flatpak on Zorin OS.
So running "flatpak update" now. I'm not a flatpak kind of guy, so had to refresh my memory by looking at the man page for flatpak.
