Have Windows 10 operating system, but can no longer use Outlook with Firefox?
Something has happened to my Firefox Browser and I cannot open Outlook which I have been using for years?
The Dialog Box says I need Windows 10, but I have had windows 10 installed, ever since it came out?

I'm in hotmail daily with no issues. see screenshot Can you show the issue and hide any personal info. Hard to help with something we cannot see.
