This just started October 30th. I am running Thunderbird 140.4.0esr (64-bit) on a Windows 11 Pro 24H2 on a PC and Laptop. Thunderbird email can no longer access my Yahoo Mail Plus account and I get a pop up windows stating Edge: Too many requests several times. I tried deleting the account and trying to reinstalling it back in but I get a error message in yellow pop up box in the account page stating "incorrect password or username". I have also tried to generate a tried party app password in Yahoo mail Plus web client and using that in place of my regular password with the same error message. I can no longer add this account into Thunderbird and I am not able to use my Yahoo mail plus account. This has occurred on both my PC and Laptop. I am fairly certain this has to due with Yahoo Mail's new security policies. I have checked the current setting are correct according to the latest FAQ & Help articles and see many others just starting see this same issue. Please provide me with solution so I can resolve this issue.
