When using Firefox, I can't open a PDF using Adobe Reader, even though Adobe Reader is selected in Firefox options. I'm using windows 10 64 bit. Thank you....

Hi, what do you have set as default in WIn10 ? Please go to Settings --> Apps --> Default Apps and see what is set to open them please. If it is not Adobe please Click the PDF ICON that prob has Edge in it and change to Adobe DC. You may have to reboot to see what happens.

The Win 10 setting is Adobe Reader. Also true in Edge, which I never use anyway.
