"Close the app to avoid disruptions" is just laughingly stupid. This is a bit harsh to say it this way ... but it is. Yet another point, which is related to all the valid remarks already done: it is quite painful to have this notification seconds after Firefox had been launched. Why the update system did not notice Firefox required an update before it launches it? Technical points left aside: when an application requires an update (Chrome, IE), it performs it before launching, not after it has launched.
