When my Firefox browser is open and I open a saved PDF file (previously converted and saved from a Word document) it opens in the browser as a Word document. Also, Word files open in the browser. I have changed the action from the content type in the General Section under Options to use my PDF and Word 16 applications. I noticed that the content type for Word is MS Word 1997-2003, which is pretty old and not sure why that would be the content in 2020. Could this be causing the issue? This is frustrating because I want to be working within the applications themselves and not in a Firefox tab. Attached is two screenshots of the Applications in the Options General section that show all the application options.
