I have two Mac systems. An M1 2020 MacBook Pro and a 2014 Intel Mac mini, macOS Monterey on both systems. I use the email client "Postbox" which is based on Thunderbird. When I saw the announcement for Thunderbird 115 Supernova I thought I'd give it a try. Installed on the MacBook Pro, played around a bit but ended up uninstalling it. Now on the MacBook Pro, I keep getting the attached image where the email body should be. It only happens on the MacBook Pro, so I'm thinking it must have something to do with the Thunderbird installation/removal. What do I have to do/delete/change to have this go away? Thanks.
