How to disable the built-in PDF viewer and use another viewer

If you'd rather not use the built-in PDF Viewer, you can use another PDF viewer like Adobe Reader, Nitro PDF Reader or Sumatra PDF.

To switch from the built-in PDF viewer to another PDF viewer:

  1. At the top of the Firefox window, click on the Firefox button and then select Options
  2. Select the Applications panel.
  3. Find Portable Document Format (PDF) in the list and click on it to select it.
  4. Click on the drop-down arrow in the Action column for the above entry and select the PDF viewer you wish to use.

Note: If you want to view PDF files in Firefox using a plugin, instead of in an external PDF reader application, select Use PDF reader name (in Firefox).

  1. Click OK to close the Options window
