How Can I Prevent Firefox and Google Chrome from Automatically Opening PDF Documents?

IN THIS ARTICLE:
Learn why Firefox and Google Chrome automatically open PDF documents in your web browser and what options are available to prevent it.

Why does Firefox/Google Chrome automatically open PDFs in my browser?

Both Firefox and Google Chrome have built-in PDF viewers. In their default state, both will attempt to open any PDF documents directly in the browser for viewing purposes.

If you find that displaying PDFs within your Web browser is causing issues, you may want to download the PDFs and open them in an external program. To disable having the browsers automatically open PDFs with their built-in viewer, follow the instructions below.

Forcing PDF downloads in Firefox

  1. Type about:preferences into the address bar to open the Options screen.
  2. Scroll to the Applications section.
  3. Type "PDF" in the search box.
  4. Under the Action drop down menu, select Save File.
  5. Click OK.

Forcing PDF downloads in Google Chrome

  2. Expand the Additional Content Settings area.
  3. Click the PDF Documents option to expand it.

More Helpful Hints

After following these instructions, all PDFs generated in iClassPro should download to your computer when you click on the Background Task. (If you have enabled the option to ask you to decide where to save each downloaded file, you will be prompted to choose a download location. Otherwise, the file will be automatically downloaded to the default download directory specified in your browser settings.)

After downloading the file, you can open it in whichever PDF viewer you prefer. Before printing, always be sure that the document is in the correct orientation (portrait or landscape) to save on paper.
