Usage of AEAD in S/MIME in Thunderbird

I would like to report that we realized that even when sending an 
encrypted encrypted E-Mail between two Thunderbird instances, AEAD is 
not used in the S/MIME encryption, even though it seems to be supported 
by NSS. Instead the legacy CBC mode encryption, known to subject to all 
kind of manipulation attacks, is used.
