The Firefox browser does not display PDF with version 1.7

[thiagoaf19]

Please, I would like to know how to solve this problem.

The external user uploaded a PDF file of version 1.7 to the system, but our system does not display this PDF in Firefox, it just displays a blank page. In Chrome and Edge the file appears correctly.

Does anyone know what it could be? And how can I solve this problem, so that this incompatibility is resolved in Firefox?

Do I need to change or add something related to JavaScript in the .tpl?

Thank you

I identified the PDF versions, but I do not know how to act to resolve this impasse.

It's possible that the PDF file triggered a bug in Firefox. It's difficult to see what's happening without seeing the actual PDF file.
