Hi, starting this morning I suddenly did not have a SEND button in Thunderbird 143.0 (on an iMac) when I tried answering an e-mail, same for forwarding or wring an e-mail. There was no update that I know of. I tried reinstalling Thunderbird, but this did not help. Several online forums mention the topic, but often from many years ago and therefore older versions. e.g. one video suggested switching on a Toolbar, that no longer exists in this version. As far as I can tell - no changes in any toolbar have an effect on what I see INSIDE an unfinished e-mail. So, I am completely blocked from doing any e-mails until I can figure that out. PLEASE HELP!
