Hello. I am using Thuderbird 68.9.0 (and daily asked for updating) and Enigmail 2.1.9 and Windows 10 pro. It was recommended not to run the auto-update for a new TB-version because of possisble conflicts with Enigmail. In the meantime there are many "news" about this topic but I am not an expert on this just a user and I have to continue with a "secure e-mail system". So I need a final statement which updates can be / have to be installed without running into trouble, losing the security or invalidating my keys. A clear working recommendation would be very welcome. Thanks. Martin
