I am referring to the built-in viewer within AgileApps. It will display Word documents and PDF documents. I am sure this built-in viewer is not depending on native browser capabilities to display Word or PDF documents.
I have attached a screen capture to show specifically the functionality I am referencing.
If I click the “Download” link (circled in red in the screen capture), then I am able to download the document.
When I click on a TIFF format document, I am immediately given a download file dialog.
