This problem just started today. I have had Firefox and Outlook for years without any compatibility issues. I have updated to the latest versions of both Outlook and Firefox. Is there a way to return to Firefox 47?

https://outlook.live.com/owa/

Are you still on the old Outlook.com? The old one had different names to the left of outlook.com in the address. All accounts should have switched over by now. ??
