This release has removed the option to sign-in to my outlook dot com account using a security key. it worked just fine using version 128.13.0 esr. Tried to rollback to that version and I get "account will need to be recreated" warning message. I'm also getting "too many requests" message when trying to connect to outlook.com through the new version. Of importance, when I go through a browser and connect to outlook, no issues. Something has changed with this release of Thunderbird - which I understand is FREE and I appreciate that, however as a very long time user, it would be nice to understand what's going on.
