Dear Maintainer,
I can confirm this behavior too, with an gmail account since today.
In the morning before the update, gmail was working. Now it isn't.
This error message in german language is shown:
Die Website versuchte, eine unpassende Sicherheitsstufe auszuhandeln.
live.thunderbird.net verwendet Sicherheitstechnologie, welche veraltet
und verwundbar ist. Ein Angreifer könnte leicht Informationen
entschlüsseln, welche Sie für sicher hielten. Der Website-Administrator
muss dieses Problem auf dem Server beheben, bevor Sie die Seite aufrufen
können. Fehlercode: NS_ERROR_NET_INADEQUATE_SECURITY
regards
Reiner
