My Thunderbird v. 115.10.1 (32-bit) Been using TB forever w/ GMail accounts Primary E-Mail is missing folders and has duplicate folders, one [Gmail] is inside the Inbox another is outside. Has [Sent] Doesn't appear to contain anything in either Junk and Trash folders. But, they do when I open GMail in my browser. My secondary E-Mail has no [Gmail] folder but does have Sent Mail, All Mail, Junk, Spam, Trash (empty), Trash and 3 that I created. This E-mail seems to function more completely. Is there a "repair install" a file to edit or something else to get me back to 100% operational? Can send folder properties if helpful. Image attached.
