From 20 October, anyone with a Yahoo e-mail account will have to set up OAuth2 authentication in the e-mail client.
To do this you need to enter the client app and generate a password as shown in the figure below:
With MailNews the operation is OK.
When I open MailNews I can use OAuth2
With Thunderbird 52.9.1 it doesn't work, there is an error.
If any MSFN users who has a Yahoo account wants to take a test and report in this topic if they have different results than mine.
Thank you all.

P.S. Now, after a reboot of PC, MailNews doesn't work.
Some problems with ImgBox.
