My forward and back arrows, recent pages icon, reload current page icon, and stop loading this page icon, are not highlighted and do not work. When I open the history tab these areas are not highlighted and the controls do not work. Also every time I open Firefox a window opens saying that Firefox closed unexpectedly and would I like to restore my previous session, even though it was shut down properly. I have tried to update Firefox on my Asus eee pc running the original Linux, but am unable to.
