Michael, that Mozilla page references "Microsoft has made some changes to authentication for their hosted email services for business and academic accounts". These would be MS products like Azure, Exchange, Microsoft 365. I believe they are different animals from a free outlook.com account associated with an individuals Microsoft account. I wish I could elaborate but I have nothing more to offer other than to comment on how much these different avenues of MS email complicate an understanding of their OAuth implementation.
Those of you using Thunderbird, are you connecting to a business or academic account, or just a MS personal outlook.com account?
