In the tab "share" of the UV, you see a box with the url to the current viewer, and below an icon that links to the manifest itself.

But unexperienced users click on that icon, and are surprised to see a popup for download, either because it is Internet Explorer, or the content-type "application/ld+json" is not recognised as json.

Wouldn't it be more clear to put a textbox with the manifest url, that you can copy? Not everyone has the reflex to do right-click-copy ..

we're trying to learn our librarians about IIIF. Things like "get the manifest url, and paste it in another iiif viewer"
