Hello, Hope someone can help me to figure out how to fix the email message reading screen issue. I have Thunderbird version 140.3.1esr (64-bit), the "latest version," on Windows 11 64-bit. Everything looks good, except the email form HTML format looks very bad; it looks like design time on HTML, and any link is not clickable. Also, when I open the message, the HTML shows as an HTML file attachment (see the image), while the same email looks good in the message pane window. I have multiple email accounts; I always see the annoying yellow message telling me a "unique identity matching the from address was not found" Also, for some reason, Thunderbird disappears from the Windows status bar when I close the message, not the application, or when I click on another program.
