I am using Firefox, on a Windows 8 computer.  Suddenly, I cannot reply to any hotmail emails.  When I click on reply, or reply all, or forward, nothing happens (swirling moving things to show it's thinking, but nothing after that).  I am not directed to a reply screen.  I have tried it on different computers, using different versions of Windows, and I have not problem.  It's only my Windows 8 computer.  Everything else is fine on the computer.  What's happened since yesterday?????
