Yesterday I wrote that I couldn't write or send emails, got a funny screen when I tried, etc. Today I still can't do it through my default browser, Firefox (up to date, 19.0), but can do it through an older Internet Explorer. The symbols that appear above this message as I type are all scrambled when the funny screen appears.

Just before the problem began yesterday I had clicked on "learn more" re the switch to Outlook (info that appears opposite the Hotmail sign in box). I didn't sign up, but I did look at that for a moment. Could it have had an effect? The last problem I had w/Firefox was resolved when you gave concrete steps to follow about my browser. Unfortunately, I don't remember. But I'm wondering if it could help me now. Thanks.
