I've got a huge problem. I use Thunderbird on my Linux desktop. Made a backup copy of the profile folder before wiping the partition and reinstalling Linux the other day. Imported the backup profile into the new installation. All of the IMAP folders worked fine, but my POP folders are broken. The messages appear to be there in the folders, but they're blank when I open them (except the sent folder: that is missing entirely). This includes my entire inbox of personal email containing thousands of messages, many of which are very important, and some of which are absolutely vital. Tbird has a "repair folder" option but all that did was erase everything include the message list (got it back by reimporting the profile folder again). Here is someone else who had the same problem, but no solution is listed: https://support.mozilla.org/en-US/questions/1024340 .... can anyone help? (Please don't tell me that I "should" have made another kind of backup, or that I should switch all folders to IMAP going forward, etc. ..... that will NOT help solve the immediate problem and will just make more stressed/angry.) Any tbird whizzes out there who can save all these messages???? This is urgent.
