Under 'Application Basics' - Profile Folder - click on 'Open Folder'
This opens a new window showing the contents of your current in use profile name folder.
Exit Thunderbird now - this is important.
Look for the following files and delete them.
cert8.db - obselete file
cert9.db - currently used file
key3.db - obselete file
key4.db - current used file
logins.json - current used file
pkcs11.txt (some people report this file missing)
secmod.db - obselete file
session.json
xulstore.json
See next comment before you start Thunderbird as you need to empty cache files.
Start Thunderbird
Add yahoo and make sure all the settings are correct.
Make sure Authentication Method is Oauth and user name is full yahoo email address.
Report on results.

Whilst Thunderbird is closed - after you have deleted the files mentioned previously.
access : C:/Users/ User Account/Appdata/Local/Thunderbird/Profiles/
Please note this is the Appdata 'Local' location which the computer uses as a cache.
Be sure you are in the 'Local' and not the 'Roaming'
Delete the contents of the 'Profiles' folder.
then start Thunderbird.
keep having to reset my secure key password and tried this in "Roaming" instead of "Local" Help!
