One or two of my computers have been on for about five years. The laptop I use mostly has been on for several months. But I’m a very teched-up person. I’ve got computers in various forms all over the place. Actually less nowadays compared to many years ago. I don’t shut anything down because I’ve got various services in operation 24/7.
Firefox is still extremely messy on Linux. It’s split between multiple platform types (flatpak, deb, snap) and I’ve seen multiple parts start to branch off on their own due to some fault. It’s really weird. Can’t even describe it. Why can’t they just do things simply.
