I have been a Firefox user for well over ten years. On Friday I accessed my emails without any problem. However, this morning I could not. I checked with my service (sbcglobal.net) to confirm my password. I then went to the password manager on Firefox to see if it was the same and it was. But when I click "Get Messages" I get an error message "Sending of password for user [email protected] did not succeed. Mail server pop.att.yahoo.com responded: [SYS/TEMP] Server error - Please try again later." I have tried this a number of times over two hours and still get this message. Any suggestions.
