Name Thunderbird Version 78.4.1 Build ID 20201104231226 on Win 10

When I try to "decrypt and open" a pgp encrypted mail attachment, nothing happens. Using "decrypt and save as ..." opens the directory selector but no file is saved.

Running Thunderbird with -jsconsole provides the following error messages:

CryptoAPI.sync() failed result: Error: Not implemented

Digging in a bit deeper ... seems like this feature is not implemented yet? RNPCryptoAPI.jsm: 

 /**
  *
  * @param {byte} byteData    The encrypted data
  *
  * @return {String or null} - the name of the attached file
  */

 async getFileName(byteData) {
   throw new Error("Not implemented");
 }

 /**
  *
  * @param {Bytes}  encrypted     The encrypted data
  *
  * @return {Promise<Object>} - Return object with decryptedData and
  * status information
  *
  * Use Promise.catch to handle failed decryption.
  * retObj.errorMsg will be an error message in this case.
  */

 async decryptAttachment(encrypted) {
   throw new Error("Not implemented");
 }

Checking again with Thunderbird 78.6.0 (64-bit) Release notes states: "fixed OpenPGP: Encrypted attachment "Decrypt and Open/Save As" did not work"

But I still can't decrypt attachments, getting an error message.

Console logs "bad message, missing MDC" decryption.jsm:526:15 

 getPlaintextFromDecryptResult(result) {
   if (result.statusFlags & EnigmailConstants.MISSING_MDC) {
     console.log("bad message, missing MDC");
