Ubuntu 24 LTS distro does not support the .deb package but has a SNAP for a ported version of Firefox. Instead, I installed direct Mozilla Firefox into /opt/firefox and run the Mozilla production release. Although as an ordinary user, Firefox will NOT let me use the internal update of Firefox under Help -> About Firefox, if I login as root and into a window environment such as Gnome, my /opt/firefox/firefox will do the About Firefox update internal to Firefox -- no apt involved. Mozilla has an apt repo and method to update Firefox, presumably via the Software Updater that can be run from a regular, not root, user window, perhaps asking for the sudo password. Which approach is better: internal Firefox "About Firefox" update in a root window, or using the .dep repo using non-root Software Updater?
