Having trouble viewing PDF files on the Luraline website?

If you're using Mozilla Firefox to browse the Luraline website and the PDF's you're viewing seem to be displaying incorrectly, this may be due to your browser's PDF reader settings.

Starting in Firefox 19, Firefox has a native PDF reader. This means Firefox can view PDFs without you having to install a third-party add-on or program such as Adobe Reader and Adobe Acrobat. Firefox's PDF viewer is enabled by default. The issue is, Firefox's native viewer is still relatively "new" and doesn't quite yet work as well as Adobe's when viewing Luraline's rendered PDF's. This article shows you how to disable Firefox's native built-in PDF viewer and change it back to Adobe Acrobat.

Take note this tip is divided into two parts. The first part shows you how to make Firefox use the third-party PDF reader you have installed instead of Firefox's built-in PDF viewer. The second part shows you how to disable Firefox's built-in viewer completely. The difference is, with the first part you don't disable Firefox's PDF viewer - you just don't use it. With the second part you completely disable the viewer. Completion of both parts may be necessary in some cases.


The process of changing back to your other PDF reader is actually pretty simple. Do the following:

  • Go to Firefox 'Options'. Depending on your Firefox settings, it may vary how to get to 'Options' but most people should be able to get there by clicking the orange 'Firefox' button in the top-left corner, going to 'Options' and then 'Options' again.
  • Once in 'Options', go to 'Applications'.
  • At 'Applications' type "pdf" in the search box (without the quotes):

  • Once you type "pdf" in the search bar, you should see a PDF entry show up. Click on the drop-down menu and select Use Adobe Acrobat (in Firefox):

  • Finally, click 'OK':

Done! Now Firefox will display PDFs in Adobe Acrobat and not Firefox's built-in PDF viewer.
