The MIME type for a xslx file is coming as "application/vnd.ms-excel.12" in Mozilla 13.0.1 instead of the "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" which comes in other browsers when using fileUpload.PostedFile.ContentType

Firefox usually gets the MIME type from the MIME database registry key.

  • HKEY_CLASSES_ROOT\.xslx
  • HKEY_CLASSES_ROOT\MIME\Database\Content Type
