I have been trying for weeks to find an answer to my problem. Firefox will not display my theme correctly, though most other browsers seem to do just fine. Firefox will not display my left column next to my right-floating menu column as it is intended. Instead, it displays the left column after the menu column is finished.
Please help. It has been really disheartening not being able to find an answer.
I'm building the theme for a friend, and I've uploaded it to my server so that she doesn't have to keep it active with such a debilitating bug. Here it is: http://enricospada.com/cupcakeshow.html
The stylesheet is located at: http://www.cupcakeshow.com/wp-content/themes/frosting/style.css
Thanks in advance for your assistance.
