A few moments in the life of my Facebook situation. This happens on Firefox with or without add ons and extensions. It happens on both Most Recent view and Latest News View. If I scroll for a couple of minutes it starts doing this. Or I scroll through a few posts and there are no more posts. My wall is blank and there is intermittent text on the left hand wall. It seems like once you get a few posts in it starts up either problem. It seems like its some kind of Facebook glitch that happens when the posts I have past go into the ether, I guess it moves the other posts up and in turn screws up my wall and time that I am scrolling. Or something of that sort. It just becomes unusable. At least I am not on Facebook much anymore. Good work Facebook.
