Yesterday, I could send emails, today, 22 Feb 2019, I can receive emails but when I try to send, I get first the Connecting sending box. jpg1 Then a demand for password jpg2 then when I cancel the demand for password and return to the email, the send button is greyed out jpg3. My husband had the problem first, and I attempted for a long time to resolve it on his computer, changing settings, attempting change password, which it would not allow me to do. So decided to see if there was a problem on Mozilla, by trying to send on my computer. The results have been identical. Both computers have identical settings, apart from his email address and my email address, jpg4, I cannot believe it is just coincidence that both computers have had a problem the same day
