I use FF on Mac OS and have never seen it refuse to operate due to an update. It will sometimes popup a dialog letting me know there is an update but I can dismiss it. I tend to check for updates every couple of weeks, anyway. The update process is mostly painless though it does restart the browser. That is probably a good thing anyway. Most updates I get when I do update the browser for other reasons and it installs and update as it is restarting.
