Note: This may be fixed in some Weeks, Months, or Years, so maybe you can try first: > Thunderbird > Add-Ons > Extensions > Search for: Lightning > Install. If you use Ubuntu-Linux or a Derivative, Lightning is not included in Thunderbird 60+ and the Update will break your Calendar (incompatible, not compatible). xul-ext-lightning is not international. Search for Add-On leads to incompatible Version. Someone told, the Beta is not recommended.
