Hello, Using Thunderbird EVERYDAY with 9 email addresses inside. Recently had problems that its not showing the folders (inbox, sent and so) and that problem is for all my emails in Thunderbird. I did try to click view - folder - all and view - layout and I did try to start in safe mode and disable lighting add on and so. Nothing works. Had the problems about 2 weeks ago but suddentlig it worked again, but now the same problem. I restarted thunderbird many times and gave it time to loading and restated PC aswell. Anyone who can help?
