Did you also upgrade lightning? Every version of Thunderbird has a matching version of Lightning. This is why you say YES when asked about checking for add on upgrades after Thunderbird upgrades.
Go here and get the correct version and install it. https://addons.mozilla.org/en-US/thunderbird/addon/lightning/?src=hp-dl-mostpopular
