Question : Nav text resizing when text only zoom is checked in FF

I was at a client's showing them the website that I had tested in all browers and was looking, until I showed it to them on their computer. They had Text Only zoom turned on in Firefox and it completely whacked out my navigation making the font too big and the nav overlap. Is there a way to stop this from happening? I noticed on cnn.com's website their navigation text doesn't resize. Any help would be great. Thanks! Attached is my CSS for the nav bar.
