Thunderbird gmail stopped working suddenly yesterday

I have three gmail accounts on Thunderbird and two of them are not working now. I also have these accounts on Apple Mail and they continue to work normally there so I know that gmail accepts my passwords.

But when I try to use Thunderbird, it keeps telling me: "Mail server pop.googlemail.com responded: Username and password not accepted".

I keep reentering the passwords and they keep being rejected. I read the FAQs about this and tried to follow them but it does not work. There must be a problem with a recent update for Thunderbird because it's been working fine up to now.. What must I do??

I just wasted a full two hours running in circles trying to follow the recommendations of the "experts" above 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
