Thunderbird, which was developed by the Mozilla Foundation, is a free and open-sourced email and personal information manager. It helps many users across the globe to manage and efficiently organize their emails. It supports emails protocols such as POP, IMAP, LDAP, and file formats like MBOX and Maildir. But there are situations where users must switch to a new system since the previous one has been damaged or become obsolete. To keep the working process smooth, it becomes necessary to back up and restore Thunderbird emails to a new computer.
