PDF files not showing up with Firefox

We are sorry that this is an inconvenience to you. Unfortunately it is out of our control and is an issue on the individual’s browser preferences because of a bug in the current version of Firefox. Firefox is now using their own PDF viewer and it does not work on some PDFs.

Current Firefox versions have enabled a built-in PDF Viewer that doesn't have all features that other PDF readers like the Adobe Reader have or may not function properly otherwise.

In order to change the default reader for PDF files (to not open PDF files with Firefox's internal PDF reader), follow these steps:

  1. Go to Tools > Options (or Firefox > Options).
  2. In the Options window, select the Applications tab.
  3. Find Portable Document Format (PDF).
  4. On the right-hand side you should find an Action column. Use that to select your favorite PDF reader. 

If you continue to experience complications or are unable to modify your settings, please contact technical support in your area.
