messages

The messages API first appeared in Thunderbird 66 (see bug 1488176). The archive function was added in Thunderbird 68 (see bug 1529785).

Note

When the term messageId is used in these documents, it doesn’t refer to the Message-ID email header. It is an internal tracking number that does not remain after a restart. Nor does it follow an email that has been moved to a different folder.

Permissions

  • messagesMove “Move, copy, or delete your email messages”
  • messagesRead “Read your email messages and mark or tag them”

Note

The permission messagesRead is required to use messages.
