By "problem" I meant having to close Firefox before further browsing, not automated updates - I don't know if I could stand daily-driving a system with Snap updating my stuff while I'm trying to use it tbh, that's one of the main reasons I left Windows behind.
Your first comment gave me the impression that Firefox required a restart because it's distributed officially through Snaps or something, idk 27 days have passed since then
To a slightly lesser extent, that's also true of Windows - severe malfunctions are less likely to happen, but when they do happen, fixing them is almost always an absolute clusterfuck, and when it isn't, it's downright impossible.
