I'm running Thunderbird 128.5.1esr (64 bit) on Macos 14.5. The Window menu in Thunderbird (at the top between Tools and Help) displays a list of open messages. I believe it used to list the messages' titles in the list. Not now. Now all it lists is "Mozilla Thunderbird" for each open message. No way to distinguish which message is listed. I tried Troubleshoot Mode... with no effect.

Is there a setting that I need to change to restore what I believe is the old behavior?
