</p>So, I seem to have found a workaround for the problem where the new Firefox built-in PDF viewer does2013-03-14T20:44:36-07:00rforgaardhttps://support.mozilla.org/vi/questions/950946?page=3#answer-417389<p>So, I seem to have found a workaround for the problem where the new Firefox built-in PDF viewer does not display PDF documents properly, that <strong>does not require your end-users to change their Firefox configurations</strong>.
</p><p>NOTE: This workaround <strong>does not work with PDFs that are fillable forms</strong>. Also, obviously, the right solution is for Firefox to display all PDFs correctly without requiring a workaround. The suggestion below is just a stopgap measure.
</p><p>I had a PDF file, from one of our contributors, that needed to be posted to our web site. When viewed in Firefox, the PDF file resulted in the dreaded message, "This PDF file might not be displayed correctly." And, indeed, it wasn't.
</p><p>So, here's my workaround. I'm using Adobe Acrobat XI, but I imagine this trick would work with any version of Adobe Acrobat. I opened the PDF file in Acrobat. I then did a File | Save As to save the PDF file in TIFF format. This created one TIFF file for each one of the pages. Then, I used the feature in Acrobat to combine multiple files into a single PDF, to combine the multiple TIFF files into a single PDF. Finally, I saved that resulting PDF file.
</p><p>NOTE: Newer versions of Acrobat will ask you, when you combine the TIFF files into a single PDF, if you would like to make the text in the file searchable, even though the pages are in TIFF (image) form. I answered Yes. At that point, Acrobat does an OCR pass (which works reasonably well) to identify the text in the new PDF file and make it searchable.
</p><p>This resulting PDF file displays fine Firefox. This is kind of cheating, because it's really not a scaleable, full-featured PDF anymore. It's simply a PDF file that happens to consist of TIFF images that match the pages in the original PDF file. But for most users, they won't notice the difference. if you need a workaround in a hurry until this problem gets cleared up in Firefox, this seems to do the trick.

<p>You will obviously be interested in your own or your favourite sites, but if you are aware of important heavy use sites having problems that may be interesting to know also.

<p>The two above may not be examples of problematic pdf forms of course.

If an user uses the built in PDF viewer, few js files (10n.js, pdf.js, debugger.js, viewer.js) exit in the ContentDocument's scripts collection (I display the pdf inside an iframe) and PDFView exists in the contentWindow. On the other hand, if an user uses the adobe acrobat plug-in, those js files do not exist in the ContentDocument's scripts collection and PDFView does not exist in the contentWindow. With that, maybe check the Element's ContentDocument scripts collection / PDFVIEW and act accordingly.
