My facebook doesn't display notifications?!?

[Jea Answer]

It is not your facebook settings!!! I ran into the same problem you did and my solution was very simple. I'm going to take a guess and say you're using Mozilla... Mozilla is a good web browser but some versions on a few different computer do not display all of the the screen even when expanded. I noticed that sometimes i could see the very tip of the notification box but for the most part it just never showed up... My solution would be to definitely get a different web browser; I would have to recommend D/L Google Chrome!!! Best Browser and has a lot of options and features. It will take you 2 min and you will be pleased. & at least you will see your little red box on the bottom right side of the screen.
