Expanding image problem in FireFox

While starting a new layout for my site, I've come across an odd problem that I've never had happen before. And this time it only occurs in the FireFox browser. In the past I have coded every one of my layouts to have expandable content/navigational areas by using 'height="100%"' on the tables codes (td). This time though, the main content area is not expanding with the navigation bars and the images around it that are sposed to stretch are not stretching.
I've tried to figure out what I had done differently with no success.

Edit: The problem solved. It wasn't a coding error but an error I mad while slicing the layout in Photoshop. Mods can feel free to delete this post if they wish too.

You might never see this but please do not use tables for layout, they're for tabluar data ONLY. Learn how to float divs to get your desired layout
