Tbird folders disappear.
In tbird I have my received emails organized into 100s of folders and subfolders. But during the last few weeks, many folders disappeared. In safe mode they seemed to reappear, once only. Then back in normal mode, they disappeared again. What's the problem and how do I fix it.
