This would be immensely more helpful if you would EXPORT this package to a CAB file (without the BINARY FILE), and post the CAB file as an attachment.
That way I can inspect the package in the Package Wizard, which will be exponentially faster than trying to manually parse this XML from a forums post. :-)
One additional question: Have you actually installed the Korean Firefox on a Korean-language instance of Windows and visually verified all of the registry keys, values, pathnames, filenames, and version numbers?
