Thunderbird updated this am on my laptop to a 102 (version?) and after can't download my mails from a POP3 account that was previously working fine. It shows the message: "Unable to establish TLS connection t POP3 server. The server may be down or may be incorrectly configured. Please verify the correct configuration in the server settings for your mail server in the Account settings window and try again" I don't see what I can change. This mail server was working fine before Thunderbird updated its version, so the problem lies with thunderbird and not with my mail server settings. Has anyone had this problem and what does Mozilla propose as solution? If not, it should not ask us to restart and update to a new version if it can't guarantee access to mail servers that were working fine. Thanks
