Reading from articles, I found out that input[type="file"] have unique views across different browsers. 
I'm looking for a quick fix for this issue using CSS(only if possible) because I need to adjust only the width of the element.
Here is the site (http://210.48.94.218/~printabl/contact/) I'm currently working with. If browse the page with firefox, the page view gives undesirable output.

Q: How can I adjust the width using CSS? Or any easiest fix for this issue.
