I can go into Google Chrome or Opera for example and then while on internet, find some website from which I want to print out an article or a single web page and have no issues printing, but not while in Firefox. It is not a problem with my printer! This is a desktop windows 10 computer. I have been using Firefox for everything except printing for over 18 months and have updated when I saw notice of a newer version of Firefox, but the issue still exists.
