We are a library software company that use a web based program. In out check out module barcodes are scanned in and since htey have a carriage return built in the barcode scans and then is entered into the system. This worked fine with previous version of Firefox Mac but wont with the lastest version. We scan it in word it give the carriage return or scan in any other browser then Firefox and it will work, but not on the latest version, Why?
