Adjust PDF Handling Settings in Firefox

Change your browser's application settings to open PDFs directly using the built-in viewer instead of automatically triggering a download.

Web browsers like Firefox have built-in file handling settings that dictate what happens when you click on specific file types. If the action for PDFs is set to 'Save File', you will always be prompted with a download dialog instead of a preview.

1
Open Firefox Options

Launch Firefox, click the menu button (three horizontal lines in the top-right corner), and select 'Settings' or 'Options'.

2
Locate Application Settings

Navigate to the 'General' panel and scroll down to the 'Applications' section.

3
Find the PDF File Type

In the list of file types, locate 'Portable Document Format (PDF)' and select it.

4
Change the Default Action

Click the drop-down arrow in the 'Action' column and change it from 'Save File' to 'Open in Firefox' or 'Use PDF plug-in'.

Adjust PDF Handling Settings in Firefox
Instant Preview Enabled: Changing this setting will force Firefox to preview the PDF immediately in a new tab without prompting you to save it.

Frequently Asked Questions

Why does Google Chrome download PDFs instead of opening them?

Google Chrome has a specific setting for handling PDF documents. Go to Settings > Privacy and security > Site Settings > Additional content settings > PDF documents, and select 'Open PDFs in Chrome' instead of 'Download PDFs'.

How do I stop Microsoft Edge from automatically downloading PDFs?

Open Microsoft Edge Settings, go to 'Cookies and site permissions', scroll down to 'PDF documents', and turn off the toggle switch for 'Always download PDF files'.

Can I force PDFs to open in a desktop application instead of my browser?

Yes. In your browser's PDF application settings, you can change the default action from 'Open in browser' to 'Use Windows default application' or specify your preferred installed PDF software.

Why is my PDF file saving as an HTML file instead of a PDF?

This usually happens if you right-click and try to save the entire webpage instead of using the website's designated download button for the PDF. Ensure you are clicking the actual PDF link or the download icon provided inside the document viewer.
