Microsoft 365 sign in window not appearing properly
I am changing the password authentication on two email accounts (two different Windows laptops) from "normal password" to "Oauth". Same version of TBird on each laptop. As the last step in this simple process, a GoDaddy window/web page pops up asking to verify Microsoft365 account credentials. On one laptop (Win7), this window contains a normal display with fields to enter password, etc. I am able to complete the process on this laptop, and it works fine. On the second laptop (Win11), the process is the same, and the same window appears, but it is blank. There are no fields to enter the required data. I've worked on this for a week now, changing default browsers, various settings, and have spent much time on the phone with GoDaddy support, all to no avail. I suspect the problem is in TBird, but I have no idea how to find it. Support for "Normal Password" authentication has been dropped, so this email account will not work until I change authentication to "Oauth". Help.

Blank web pages are often caused by so called security products. Kaspersky, Webroot et. al.
Thunderbird is built on the "mozilla platform". This means that for these oAuth pages that issues that affect Firefox probably apply to Thunderbird as the underlying tech is the same. In this instance, Thunderbird is acting as a web browser, using web ports, so the security software can be confused and even block it.
Thanks for your response. I (temporarily) turned off my anti-virus protection, but that didn't help.
However, I have circumvented the problem by creating the Oauth2 account on the Win7 laptop, then moving that profile to Thunderbird on the Win11 laptop. The Oauth2 account now works on the Win11 Thunderbird. Now if I could just figure out how to get all the emails from the (saved) old profile into the new...
