Duplicate e-mails
I have 4 e-mail addresses and corresponding inboxes. One is my personal addy that I use for most legitimate business. The other 3 are leftovers from former businesses and a spam addy. I use those other 3 addys sparingly, but only for sites I want to maintain distance from, and any I suspect might be spammers.
Thunderbird has worked wonderfully for me for some years, but recently, I have been getting duplicate messages in 2 of my 3 dummy accounts for every one that is legitimately sent to my main account. None ever show up in that 4th account, but I did just receive an e-mail that was intended for that 4th account, and the inbox acted as it should (no duplicates anywhere).
I have spent a couple of hours with a very dedicated service rep from my ISP, and she was unable to find any solution. She suggests that reaching out to Firefox is the next logical step.

Do the dummy accounts have unique login addresses online? Or are they aliases of the main account? What are incoming server settings for the dummy accounts and the main account? Knowing that may help. Thank you.
I shouldn't have referred to them as dummy accounts; they are all independent login addresses, not aliases. They are all collected together with separate inboxes etc. in Thunderbird. I meant dummy only in the sense that they are used when I don't want to disclose my personal addy, or when I want to collect conversations in a separate place.
The server settings, if I understand what you mean by that, are identical for each account. One possible wrinkle is that, for some reason, my ISP routes all e-mail through Yahoo before collecting them and sending them to me. That has also been the case for many years. The tech-rep from my ISP was aware of that and found no issues with that connection.
When you log into the accounts online, do you see duplicate messages? I recall a person recently posting here about duplicate messages on his Yahoo accounts, but I don't know if that's relative to your issue.
Good suggestion. I can only log into my mail accounts at Yahoo 1 at a time, but when I do, they are all showing themselves to operate exactly as I want/expect. That is, there are no duplicate messages in any of my inboxes. However, it is odd that my main inbox only shows the one most recent message, and thinks it is unread, even though there are several items held there in my corresponding Thunderbird inbox, and the most recent e-mail has been marked read. It seems that at some point, Yahoo stops keeping track of past e-mails, but it takes a couple of days.
The account I am using for this exchange is the one that was not receiving duplicates. It shows both of the alerts to your 2 posts in here, just as it should. Those alerts are not being duplicated anywhere.
Can you refer me to the thread where someone was having a similar problem? Perhaps my answer lies there.
Sorry. I recall it, but there was nothing in the post's title to identify it.
