I use v102.0b5 (64-bit) on Mac OS 10.14.6 with a main password to protected my mail account passwords. When I start Thunderbird, I have to enter my main password. Problem: The little window pops up several times even while I am already typing my main password. So I have to wait a bit until Thunderbird "calms down" and re-enter the password. But even after pressing enter, it may pop up again, but usually Thunderbaird has indeed received my password and the access to my mail accounts work fine. This should be really fixed as soon as possible because it is very annoying.
