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.
Launch Firefox, click the menu button (three horizontal lines in the top-right corner), and select 'Settings' or 'Options'.
Navigate to the 'General' panel and scroll down to the 'Applications' section.
In the list of file types, locate 'Portable Document Format (PDF)' and select it.
Click the drop-down arrow in the 'Action' column and change it from 'Save File' to 'Open in Firefox' or 'Use PDF plug-in'.

Change Default PDF Viewer for Local Files
Verify your system's default application settings if local PDFs on your computer are prompting save dialogs or opening in the wrong program.
Set WPS Office as Your Default PDF Viewer
Stop dealing with frustrating save dialogs or unsupported file formats. WPS Office includes a powerful built-in PDF reader that allows you to open, view, edit, and annotate PDF files seamlessly.
- 1. Download WPS Office: Download and install the free version of WPS Office from the official website.
- 2. Open File Properties: Right-click any PDF file on your computer, select 'Open with', and choose 'Choose another app'.
- 3. Set as Default: Select 'WPS Office', check the box that says 'Always use this app to open .pdf files', and click 'OK'.
