The built-in PDF viewer introduced with Mozilla Firefox and Google Chrome do not support XFA-based PDF forms, which are dynamic pdf forms typically with fillable fields. Therefore, XFA-based PDF forms do not open in later versions of Firefox and Chrome.  HOWEVER, these PDF's display fine in Internet Explorer.

Note:  When trying to view a pdf hosted on the siue.edu domain, the built in pdf viewer in Firefox and Chrome is bypassed and you should be prompted to save or open the pdf.

  2. To use XFA-based PDF forms on Firefox and Chrome, perform the following steps to configure Firefox and Chrome to open PDFs using Adobe Reader or Adobe Acrobat.

Note!  Ensure that you have Adobe Reader or Adobe Acrobat installed on your machine.  If you do not have it installed, you can download it here:  Adobe Reader

If you are using Mac:

  • You will need to change the default pdf viewer to Adobe Reader.
  • Ensure that you have Reader installed.  If you do not, you can install it from here: Download Reader
  • After Reader has been installed, 'CTRL-Click' on the .pdf you want to view and select "Download Linked File As".
  • Save the pdf to your computer.
  • Open your documents folder and 'CTRL-Click' on the .pdf you downloaded and select "Open With" and then "Other".

You will only have to go through this process once.  All future pdf's will now open properly in Adobe Reader by default.
