Thunderbird: I miss an attachment extractor

[Martin511]

What I really miss very often is an attachment extractor to extract attachments from multiple selected mails.
Since the old AttachmentExtractor Add-On is no longer developed I hope there will be a solution for this.

(async () => {	
	const { MsgHdrToMimeMessage } = ChromeUtils.import("resource:///modules/gloda/MimeMessage.jsm");
	let getAttachments = async function(MsgHdr, resolve = null) {
		return new Promise(resolve => {
				MsgHdrToMimeMessage(MsgHdr, null, (_msgHdr, mimeMsg) => {
					resolve(mimeMsg.allUserAttachments);
				}, true, { examineEncryptedParts: true, partsOnDemand: true })
			})
	}
	let msgHdrs = gFolderDisplay.selectedMessages;
	if (msgHdrs.length > 0) {
		window.setCursor("wait");
		let a = {Types: [], Urls: [], Names: [], Uris: []};
		for (let msgHdr of msgHdrs) {
			if (msgHdr.flags & Ci.nsMsgMessageFlags.Attachment) {
				let allAttachments = await getAttachments(msgHdr);
				for (let Attachment of allAttachments) {
					a.Types.push(Attachment.contentType);
					a.Urls.push(Attachment.url);
					a.Names.push(encodeURI(Attachment.name));
					a.Uris.push(msgHdr.folder.getUriForMsg(msgHdr));
				}
			}
		}
		if (a.Urls.length > 0) {
			try {
				messenger.saveAllAttachments(a.Types, a.Urls, a.Names, a.Uris);
			} catch (e) {
				console.error(e)
			}

		window.setCursor("auto");
