They don't do this on Linux, right? Why?
Installing browsers by hand in your homedir specifically so they can update themselves and you don't rely on the system package manager seems like a fairly widespread recommendation, but maybe I'm talking to a biased set of people.
Not from me to others using Fedora, the chrome you get via
dnf install fedora-workstation-repositories
dnf config-manager --set-enabled google-chrome
Is rapidly updated.As a general rule I use what is in the repo's unless I absolutely can't or the version in the repo is so old that I can't.
