product description not displayed properly on magento

I'm having trouble fixing the product description display on my magento store. It displays just fine with chrome. However, i开发者_如何学运维t is coming on top of the product details in firefox. Have a look: http://www.chefmaha.com/index.php/default/dessert/cream-filled-basboosah.html

Any idea how to fix this?

Thank you.

You need to change this:

<div class="clear"></div>

to this:

<div class="clearer"></div>

Or add a .clear rule to your CSS.
