Thunderbird quit downloading email. I've read through a lot of people here having the same issue. But NO ANSWER FROM THUNDERBIRD. What gives?

Lets me make this very clear right now so there is no ongoing misunderstanding or wrong expectations. This is a peer support forum. Folk here are fellow Thunderbird users. There are no folk that you get to heap abuse of that are paid to make you feel good about the product. We use it and generally like it, but that is about it. Personally after more than a decade of responding to folk about not getting mail the forums are full of folk being told to look at their antivirus post upgrade and being asked for actual information about what error messages they get and what provider they use. You can not do more than guess what an issue is without information. Have you tried any of the information in the appropriate support document. https://support.mozilla.org/en-US/kb/cannot-receive-messages which discusses this extremely generic issue. "I am not getting messages" is the electronic equivalent of the "postal service did not deliver a letter today" the reasons why that may be are myriad and certainly may exceed the number of minutes in the day the delivery failed. The fundamental most common cause of mail receipt issues post an upgrade to Thunderbird is the software firewall on your antivirus product or one of the components of same that they inject into the running Thunderbird instance. It is difficult to build in reliability when external forces think they know better. Generally you do not see support articles directly blaming these products, even if such blame is earned. Then we have user resistance to the issue being anything but Thunderbird. It is the product that is not working, so of course it needs to be fixed. usually nothing is further from the truth. So I will leave you with the standard "boiler plate" request for information since you did not include anything relevant to actually trying to help you with your issue.
