Thunderbird v 38.5.0 Do I need to update ?

Removed gmail account from thunderbird.

Used firefox to go to GMail directly and logged in to verify new
password. It allowed access.

I logged out of gmail in firefox.

Back at Thunderbird and adding gmail account.
User name and password entered.

Did its thing then opened a window
Enter Credentials for (account name).

None of the links or buttons on this windows works. Nothing happns when
clicking any of them.

I expected this to open the gmail windows to say I am allowed to use
thunderbird.

How do I fix this to use in thunderbird?

Do you think that is an OAUTH2 window ?

Is yours like this ?
