» Site layout different between IE and FF.

Wondering if I could get some help with why the site layout looks different between IE and FF.
I have the latest IE and FF, which I have been viewing the site with.
The only thing that seems to be wrong is the two side areas, in FF it looks good with the left address details under the menu is at the bottom, and the right FB logo is also at the bottom of the page with no black spaces, where as when viewed in IE, they don't line up at the bottom, with two big black spaces on either side.
I've used tables to help with the layout of the site, and I'm guessing it is something with that which I need to change, to get the look right in both.
I have heard from many people that tables isn't the way to go, but it is what I have used.
Any help on where I have gone wrong, and how I can go about fixing it, so it looks same in both would be great.

Thanks in advance.

I'd recommend you to modify this 3 column fixed layout (http://www.bonrouge.com/3c-hf-fixed.php). That layout uses a faux column approach (http://www.alistapart.com/articles/fauxcolumns/) to make the floated columns appear as stretched 100% of the height.
