I have no idea how it happened. But when I opened my Thunderbird email program and with my Inbox showing, Thunderbird downloaded all my new email messages but suddenly all the email messages that was there before the download disappeared! I had not done anything yet, I was just waiting for any new emails to download. Now the only thing showing in my Inbox are the emails that Thunderbird just downloaded. I checked in all the other folders I have and the old messages are not in any of those. The first folder I checked was the "Trash" folder to see if somehow they had all inadvertently deleted and put into the trash. You would think if messages disappeared out of the Inbox that they would have gone into the Trash folder. Now I am afraid to open Thunderbird again for fear the new messages are going to disappear too!

Anyone with any ideas?
