I do restart browsers after upgrading them, but that's different from restarting Linux. For desktop environments, I usually don't bother rebooting Linux for anything other than major releases (like GNOME 43/44 and Plasma 5.26/5.27) since most of the minor releases don't make enough of a difference in day to day use to interrupt what I'm doing.
