I was recently browsing questions when this hover message appeared over my Top Bar:
I have never seen it before, nor here or on other SE sites that I frequent. What purpose does that notification serves and why could it have appeared in this case?
I noticed that the notification stayed a while, and then after some time and hard refreshing my Firefox browser it went away, but I am still baffled at what could have caused this. Just now as I am editing this post I saw the notification again, and it went away just like the other one did.
Could it be my Internet connectivity (tbh it has been slower today than other days); has anyone else experienced this?
