I am currently unable to connect to my 'comcast.net' email. It was working fine until 12:20 on Nov 29. Thunderbird had just installed the latest updates (128.5.0esr (32bit))and it seemed to be OK. At about 1430 I was at xfinity store and made changes to my cable TV package. I informed the agent about my email problem, but he wasn't able to provide any help. When I returned home, I was still (and currently) unable to connect to the email server. When I 'click' get mail the 'system' tries to connect (the little blue line in the lower right corner is active and I soon get a message 'unable to connect'). I have been into SETTINGS and ACCOUNT SETTINGS numerous times and have made some changes with no success. I am wondering if it is a password issue (how to fix?) or a change somewhere else that I haven't found. I note thunderbird has 'recently' added encrypted requirements, Is there something there I should know about? I do not use a proxy server and have set for NO PROXY on internet connections. All of my other 'normal' internet sites seem to work OK. What am I missing? appreciate any ideas. John
