When the home page is started, the "loading circle" in the upper left corner, keeps going round and round, forever. Also we have a game on Face Book, called Gardens of Time, that starts to load, then just "freezes", and the "loading circle" again goes round and round. The best we can tell, this started the other day when there was a notice to "up-date Firefox," which we did. We have tried all the normal "fixes" including completely removing power from the computer. ( Running Windows 7 Home Premium )
