I am using Firefox version 33.0 with an Ubuntu 14.04 LTS operating system. I get a 403- Forbidden: access is denied message when trying to access my Microsoft Outlook Web App (OWA) email. When I use another computer running Firefox version 33.1.1 with a Window 7 operating system, I can access my Microsoft Outlook Web App email perfectly. Does anyone have any suggestions on how to get my Firefox browser on the Ubuntu machine to be able to access my email on OWA?
