这是以下问题/答案的一种后续：https://stackoverflow.com/a/60246205/6342243
此问题末尾的代码获取帐户列表，选择emailAccountName，从wantedMailFolderType获取MessageList对象，并尝试通过browser.messages.getFull(messageId(从一个messageId中获取MessagePart对象，但始终失败，并显示以下异常消息：
[Exception...
"Component returned failure code: 0x80004005 (NS_ERROR_FAILURE)
[nsIMsgMessageService.streamMessage]"
nsresult: "0x80004005 (NS_ERROR_FAILURE)"
location: "JS frame :: resource:///modules/gloda/mimemsg.js
:: MsgHdrToMimeMessage
:: line 238" data: no]
mimemsg.js:238:16
这种行为与运行thunderbird 68.4.1(64位(的linux mint 19.3(64位以及在运行thunderbird 68.2.2(32位(的windows 7(64位(上。
这里是再现错误的代码：
emailAccountName = "firstname.lastname@email.com";
wantedMailFolderType = "trash";
console.log( tstamp() + " Entered Main Program" );
function tstamp () {
let d =new Date();
return "" + d.getMinutes() + ":" + d.getSeconds() + "." + d.getMilliseconds();
}
function accountsList_successCallback( arrayOfMailAccount ) {
console.log( tstamp() + " Entered accountsList_successCallback()" );
let accountId = false;
for (let i = 0; i < arrayOfMailAccount.length; i++) {
if ( arrayOfMailAccount[i].name == emailAccountName ) {
accountId = arrayOfMailAccount[i].id;
break;
}
}
console.log( tstamp() + " Leaving accountsList_successCallback(), returning accountId: " + accountId );
return accountId;
}
function mailAccount_successCallback( mailAccount ) {
console.log( tstamp() + " Entered mailAccount_successCallback()" );
let mailFolder = false;
for (let i = 0; i < mailAccount.folders.length; i++) {
if ( mailAccount.folders[i].type == wantedMailFolderType ) {
mailFolder = mailAccount.folders[i];
break;
}
}
console.log( tstamp() + " Leaving mailAccount_successCallback(), returning mailFolder: " + mailFolder.type );
return mailFolder;
}
async function getMessagesList( mailFolder ) {
console.log( tstamp() + " Entered getMessagesList()" );
let page = await browser.messages.list( mailFolder );
let messageHeader = page.messages[ 0 ];
let messageId = messageHeader.id;
console.log( `Trying to .getFull( messageId == ${messageId} ) MessagePart object now...` );
let messagePart = await browser.messages.getFull( messageId );
console.log( tstamp() + " Leaving getMessagesList()" );
}
browser.accounts.list()
.then( accountsList_successCallback) // after .accounts.list() Promise is fulfilled...
// accountsList_successCallback is called, which
// in this example returns the accountId string...
.then( accountId => browser.accounts.get( accountId ))
.then( mailAccount_successCallback) // after .accounts.get() Promise is fulfilled...
// mailAccount_successCallback is called, which
// returns the wanted MailFolder...
.then( getMessagesList ) // ... passed to getMessagesList(), which successfully
// awaits a MessageList object...
// but every call to .getFull( messageId ) fails.
.catch( finalCatch )
;
function finalCatch( error ) {
console.error( "ERROR passed to finalCatch() : " + error);
}
console.log( tstamp() + " Leaving Main Program" );
这是上一次运行的输出(popup.js中的行号xx被删除，因为它们与此摘录不匹配(：

有人能在他的机器上试用一下吗？如何继续？BugZilla上的bug应该被报告吗？
提前谢谢。richard
问题解决了！
只有当另一台活动电脑上的同一IMAP帐户有另一次登录时，才会引发异常。似乎只要同一个电子邮件帐户同时有多个登录或会话，就会引发异常。
抱歉打扰了。
非常感谢您的关注。richard
