如何在Firefox浏览器中更改字体大小

Question

My website works great in every browser except for Firefox. For some reason the browser increases the size of the text larger than any other browser and it pushes the text out of its div. How can I make the text smaller for only Firefox?

I have tried this code but it did not work,

 <script>
    if ($.browser.mozilla) {

        $('.first_develop_div').css({
         'font-size': '12px'
        });
        $('.second_develop_div').css({
         'font-size': '12px'
        });

    }//end if firefox

  </script>
