I've noticed that sometimes updates to Firefox cause it to stop working until it's restarted. If you're writing a long message, or filling in some form, or if you have an order confirmation page open, then you might lose that data. I've never seen that happen in native GNU/Linux applications, though. I guess it might be related to the XUL stuff in Firefox. But given that Firefox (and Chrome/ium) are memory hogs that eventually get OOM killed, you need to restart them periodically anyway, so it might not make a big difference if the OS does auto-updates in the background.
