When I try to download a pdf it will display, which looks different then it used to. The web page shows a notification line that says This document may not be displayed correctly. Also the print and save pop up does not show anywhere.

Current Firefox versions have enabled a new build-in PDF Viewer that doesn't have all the features that other PDF readers like the Adobe Reader have.

You can change the action for Portable Document Format (PDF) from Preview in Firefox to use the Adobe Reader or set to Always Ask in "Firefox > Options > Applications".

You can set the pdfjs.disabled pref to true on the about:config page to disable the build-in PDF viewer.
