If inline viewing is not supported the PDF is downloaded and may then be handled by some external application.
Note:This method replaces a number of legacy methods of inferring support for inline viewing of PDF files.
Value

js
if (!navigator.pdfViewerEnabled) { // The browser does not support inline viewing of PDF files.}Specifications
