Since I moved to latest TB level 78.2.2 I get the error message 'Connection to server was interrupted' when I try to receive emails.

I have had this problem since 11/29/2020. No emails received since that date. Provider is att.net. Have tried several of the suggestions here to no avail. My mail is available on the web, no problem.

What is the Mozilla response for a solution?
