'Some time ago I suddenly stopped being able to log into my Aetna health account on the Aetna web site. When I typed in my user ID and password I get the following message: "System temporarily unavailable. Please try again later." It's been like this since last March. I just now tried logging in on my IPad and Microsoft Edge and had no problem logging with either one. This means that Firefox has to be causing the problem. How do I fix the problem?
