For some reason, when I logged on today using Firefox, your website is broken. All the menu items normally across the top--like "Catalog," "Community," etc.--are now running in a multicolored line vertically down the screen. Further, each menu item is broken down into its sub-menu navigational components (like "Boardgames, RPGs, LCCs," etc., under "Catalog") and are also displayed in this vertical column. The column is slightly in the background but still quite visible.
This is a firefox problem or perhaps a new problem in the interface between your website and firefox, as when I access you via Internet Explorer, everything is working properly.
This problem is not evident on any other website when using Firefox.
