Google continues to improve PDF Reader features and capabilities in the Chrome web browser. To the latest, the company added support for XFA-based PDF forms. Here’s how you can open XFA forms in Chrome PDF Viewer.
What is XFA?
XFA stands for XML Forms Architecture. XFA forms are embedded inside PDF documents, the user can fill the data and print them.
You can type data in the XFA form, but you can’t save it. For future reference, you may want to take a print of the completed form.
How to know a PDF is an XFA?
Your PDF Viewer may display this information if it doesn’t support XFA forms.
As of writing, Firefox and the new Microsoft Edge don’t display this type of PDF form.
“If this message is not eventually replaced by proper contents of the document, your PDF Viewer may not able to display this type of document“.

It’s obvious Adobe Acrobat DC supports this PDF.
If you want to open all types of PDF documents, then you should be using PDF Reader from Adobe and Chrome, in the future.
