MS Teams does not work properly on Firefox for example (I’m forced to use it once in a while for work). Same with other web-apps that often don’t function correctly.
On Android Chrome manages to stay open while multitasking while Firefox will close the tab 90% of the time requiring reloading the page. That’s especially annoying during check-out or logins when I need to switch to a 2FA app.
This is why you should keep backups, which, for me, includes physical printouts of access data stored in a safe location. That’s also helpful if something should happen to you.
