Hi I'm using Thunderbird 78.2.2 on a Win 10 machine and when I go to send an email and press the "send" button nothing happens and I get a popup window that appears on the top right under "check" that lists recipients and asks to "send or cancel". How do I disable this feature? it's a complete pain in the rear if you get my meaning! I have attached an image of the problem. I've never had this happen before.. it just started maybe with this version. I can NOT find any setting to remove or stop it from happening. No messages are sent until you hit "send" in the popup window. NO emails can be sent unless you go through this step. Many thanks in advance... I hope someone can help me.
