Recently a selection of my email folders no longer appear in Tbird. It included trash and sent but also many local folders that I have created. I use Pop but these folders are local and not synched to anything. I have tried removing the the two files (msf and the second one without an extention (mbox ?)) that appear in the mail storage folder, recreating an empty folder and replacing the generated folder with the original file. Next time I open, still no folder. I have not tried moving and then recreating the panacea.dat and global-messages-db.sqlite files, though I have seen that suggested. Or the folderTree.json The mail is all still there when I search for it. I have tried repair folders. Nothing. I have tried showing hidden files - nothing. How can I get Tbird to rebuild properly? Thank you
