Hi, Bill. With Thunderbird, you may want to have Yahoo generate an "app password" Here are instructions for you: Substitute "Thunderbird" for "Outlook" in the instructions. https://forums.cox.com/discussions/apps/how-to-use-cox-e-mail-transitioned-to-yahoo-via-outlook-/152689
Looks simple enough, though annoying and non-intuitive. Thanks for following up. Is the idea that this would be done INSTEAD OF the OAuth thingy, or IN ADDITION TO it? What security settings need to be specified in Thunderbird? "Normal password", etc.
The password provided by the Yahoo procedure will become the password.

Thanks for sticking with me. Getting closer. Reminder - Windows 11, T-bird 115.11.0 64 bit.
I have 5 Cox.net accounts, and all have transferred successfully to Yahoo. I am now trying to get them into T-bird. I followed your App Password procedure to get the first account into T-bird. It worked easily and I was happy, so I set out to get the second account into T-bird. I used the same settings as for the first account, of course, but encountered a problem with the SMTP entry. The SMTP part of the window defaults to Default Server, and there are no other choices. The Default Server window contained the account name for the first account (the one I just successfully set up), which of course doesn't work for the second account. So in the SMTP window, I EDITed the account name to the name of the second account, and now the SMTP server no longer works for the first account. There seems to be no way to do anything else. No way to change the choice of Default Server to something non-default. No way to add a second entry to the SMTP server list. No way to delete an entry. If I leave the account name blank, hoping that it will work for all accounts, none of them work.
An Internet search suggests that there MAY be a bug in T-bird 115 - but the discussions are pretty murky and without conclusions. Before I dig myself in even deeper, I thought I would impose on you once again for suggestions. Thanks for anything you can offer.

A bit more - Before the Cox-to-Yahoo transition, the Account Settings in Thunderbird for all 5 of my Cox accounts pointed to something called the SMTP Default Server. This Default Server listed the Cox SMTP server name and port, but I don't think it included an account name. In other words, all my accounts could point to the same Default Server, as long as each account supplied its own password upon use.
Thunderbird stored the individual account passwords in an internal password table (Tools>Settings>Security>Passwords>Saved Passwords>Show Passwords). Each account (email address) had two entries in the table - one naming the Cox POP server, and one naming the Cox SMTP server. The SMTP entry in the table included the account name (email address) and the password for that account. My surmise was that when I send an email from a given account, Thunderbird grabs the server name and password from the table, and forwards them to the SMTP server along with the outgoing message. The server would then compare the account name and password with its own record, stored (and visible) at Cox.com.
Summary: I have now tried to add the first two of my 5 cox.net accounts to T-bird, using Account Passwords as you suggested. In both cases, the incoming (POP) half of Thunderbird works as it should. The outgoing (SMTP) half remains a problem. Unless I mis-remember or mis-understand something, the thing that is different today is that the definition of the Default SMTP Server now includes a specific account name. I need a way to specify the Default Server without an account name, or a way to set up multiple non-default SMTP servers. Neither appears to be possible. I don't know what to do next.
