PDFObject stopped rendering and automatically downloads #275

Closed 365ging closed 2 years ago

This week the PDFObject that I have had implemented for a few years started not rendering in any browser and automatically downloading. The url that I'm using is from Azure Blob Storage. I have not changed the code at all. Is there any reason this would be happening?

PDFObject never forces PDFs to download. In my experience, if the PDF is no longer displaying inline, and is automatically downloading, it's usually due to the server's Content-Disposition header settings. Check your server and/or the server-side code that requests the file and ensure Content-Disposition for PDFs is set to inline and not attachment. See https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Disposition for details.

Some browsers also enable users to change how PDFs are handled. For example https://support.mozilla.org/en-US/kb/view-pdf-files-firefox-or-choose-another-viewer I once accidentally set Firefox to automatically download PDFs instead of rendering in a new tab (though this shouldn't affect PDFs embedded via PDFObject within an HTML page).

Good luck
