Why can I not all of a sudden get a website that is a PDF to open up so that I can look at it then I CAN DECIDE if I want to download it as a PDF file. I recently discovered that when I click on the link the PDF is automatically being downloaded to my download folder every time I clicked on the website link - this problem is very irritating & so is your so called help page!

Could you check your setting for PDFs: View PDF files in Firefox or choose another viewer. Does the "Open in Firefox" work on yours?

Firefox 78+ releases offer a choice to open PDF files that would normally be saved or opened in an external application in a Firefox tab.

See "What's New" in the "3-bar" Firefox menu button drop-down list.

You can control this feature via a pref on the about:config page.

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.
