However, Microsoft Edge PDF Reader is the default app for opening PDFs in Windows 10. So, sometimes when you open a PDF file on Firefox with the system viewer, you might be using the Edge PDF Reader.
This guide will show you everything you need to know about the feature and how to use it.
Does Firefox have a PDF Reader?
Firefox has a modern PDF viewer that allows you to view and read PDF files within the browser. It is the default PDF Reader on the browser and will help you open your files when you click on them.
However, Firefox allows you to download and change your PDF viewer and use the Windows default option.
Quick Tip:
If you work with lots of PDFs and need easy access to view and read them, we recommend Adobe Acrobat Reader for this job.
Adobe Acrobat Reader is a free app that gets you the best viewing experience for all types of PDFs. Also, it comes with fill and sign options for important documents.
How can I open Firefox’s downloaded PDFs using Edge PDF Reader?
Use Open in System Viewer or Always Open in System Viewer
Gone are the days when you required Acrobat Reader to open PDFs. With common browsers like Chrome, Edge, and Firefox offering built-in PDF readers, you no longer have to deal with the troubles of installing or troubleshooting Acrobat Reader.

Simple and fast PDF viewer lets you access files from any device.
But each browser’s PDF reader has unique features, shortcomings, and strengths. Well, Firefox lets you use Open in System Viewer or Always Open in System Viewer to read downloaded PDFs.
To do so, press Ctrl + J in Firefox to access the PDFs you downloaded using the browser. When you right-click on a PDF, the context menu that comes up includes the new options for viewing PDFs:
- Open in System Viewer: This option lets you open the document in the default PDF reader just once.
- Always Open in System Viewer: This option lets you view PDFs in the default app. Therefore, clicking on a downloaded PDF opens it right away, always.
Of course, you can set the default PDF viewer to another app instead of Microsoft Edge PDF Reader in Windows. In that case, the other app you select will launch your PDF documents if you choose any of the Open in System options in Firefox.
The Edge PDF Reader itself received new enhancements recently, including the ability to highlight words or sentences when reading a PDF.
Why won’t Firefox open a PDF?
If Firefox doesn’t open a PDF file in the browser window, it might be because of your settings. If the browser is set to download PDF, Firefox will need to download the file before you can open it from the downloads folder.
