Outgoing email stops in DomainCheck

Ever since the latest automatic Thunderbird download on 11/2/2020 Thunderbird started stopping all my outgoing emails at DomainCheck. It shows the "send" button as as an inactive button does not allow me to click it. I have multiple accounts with Gmail and Outlook, and every account has the same problem. I am still receiving all emails without an issue. Is there a setting I can choose to skip the DomainCheck entirely just to make my email work again?

Just found the cause myself. Apparently it was the extension Confirm Address that perhaps is no longer compatible with the latest version of Thunderbird.

What is DomainCheck? There are several browser plugins with that name, but it's not part of TB. I suggest you disable or remove it and do any checks manually on a per-domain basis.
