Last week, when I tried to sign out of Hotmail I got a message that sign out would not complete. Since then I have been unable to sign in to Hotmail in Firefox. This happens only in Firefox. I can sign in and out of Hotmail in Safari. My computer is an iMac, i3. Here is a link to a screen shot of the message from Hotmail.
