Output Results of Website Not Showing

[rempx]

Hello,

We have a website (remtopxonline.com) that provides an online calculator to convert REM to PX. It works fine on all browsers, but we recently noticed that it is not working on Firefox.

Our developer has been unable to find and fix this error.
