Text inside my input fields is blank on FF and IE

If you pull up my homepage in Firefox:

You’ll see the default text inside the input fields in the main email capture section shows up fine.

If you pull it up in Chrome or IE, however, the input boxes are blank

Can you help me fix this?

The form code is located inside of a “shortcode” in the Shortcodes UI section here:

Thanks so much!!
