This also concerns Tutanota allowing login BTW. I found that even with an "approved" browser set "to enhance security and privacy" the Tutanota login comes back with "Your browser is not supported". I found however, resetting the browser profile (FF in this case) by deleting the browser profile, login is restored. Strangely enough, if then the original profile is restored, login is still possible. Furthermore, I suspect that this behaviour is not user agent dependant, because "spoofing" a Tutanota accepted browser does not resolve a "not accepted browser" situation. Perhaps Tutanota can share what their login page is scanning for that triggers this process?
