I am getting an Error 50 message when I swipe a credit card. How do I fix this?
I tried two different credit cards & got the same error message

How is that related to Firefox? No such feature in Firefox, and Firefox doesn't use 2 digit error messages.
Also note that you are running a very old version of Firefox. This won't solve the issue with your credit card system (I assume you're running a Point of Sale system?) but you should update Firefox.
