Trying to connect with GMAIL
I have uninstalled and re-installed TB on a win 10 laptop. When It starts up, I add my gmail account (I know gmail now requires OAuth2) and TB configures the account. When I click DONE it goes into a never-ending loop asking for my password and when I cancel it shows a green box indicating that the password was accepted but then says there is a configuration issue and stops the addition of the account. I have matched the configuration parameters with another laptop which is working correctly in connecting to gmail but nothing seems to work. How do I connect with gmail? Thanks.

I had the very same problem just fn=inished wasting full two hours running in circles trying to follow the recommendations of the "experts" I know NOTHING of emails (and plan to stay ignorant)
The answer is in a reddit post: https://www.reddit.com/r/Thunderbird/comments/v7ziud/how_i_fixed_oauth_problems_in_a_tb_profile_with_2/ "The gmail popups won't let me enter passwords... it just refreshes over and over with the email account box. Yes the accounts are still valid and working."
Go to Thunderbird -> Preferences -> Privacy and Security In the Web Content section:
ACCEPT ALL COOKIES - it is as yet unclear whether should be only all third party etc. and how long to keep them - can one be minimalist with these cookies
This IMMEDIATELY worked and all of my mail since June 6th downloaded
