I use an iMac with OS 12.4 (Monterey). A subfolder named "Family" under Local Folders and the subfolders within "Family" have disappeared. I read a few of the solutions but cannot understand well enough what to do. I do see the folders on my computer just not in Thunderbird. Would someone please tell me how to get these folders to show up in Thunderbird again? I need someone to tell me step by step and not use any abbreviations. I am 64 and this old brain isn't what it used to be. Thank you.
