My discounts and special deals buttons look right in IE and Safari, but in Firefox the span element is too low. So I go into firebug and start disabling and enabling and tweaking and I noticed that whenever I would disable any element in the span element and re-enable it, the text would be perfectly centered like it is in IE and Safari.
How can I tell why the page is not working correctly if firebug is acting like this?
