  • Backing up your Thunderbird profile means you can restore your data in case of emergencies or system crashes. 
  • Three simple backup methods for Thunderbird profiles are backup copies, backup with the export tool, and backup automatically with third-party software.


Mozilla Thunderbird is an open-source email client that lets you access multiple email accounts, calendars, tasks, notes, and more within one interface. It is a powerful application that is highly customizable, secure, and easy to use. Millions have used it over the years. 

The Mozilla Thunderbird profile is a folder that Thunderbird created on your computer, which saves all the data from your email accounts, passwords, contacts, settings, and other configurations. So, the Thunderbird profiles are essential for keeping your important emails, passwords, contacts, and settings safe.
