Understanding Address Book Types
Thunderbird includes two main address books by default:

- Collected Addresses: Thunderbird automatically adds email addresses from people you correspond with here
You can choose which address book new contacts are saved to in Thunderbird's settings. Many users prefer to save all contacts directly to their Personal Address Book for better organization.
Additional Contact Management Tips
- From Emails: When viewing an email, click the star icon next to the sender's address to quickly add them to your address book

Thunderbird stores your address book locally on your computer, making it fast to access. You can create multiple address books for different purposes, such as separating work and personal contacts. The contact sidebar in the compose window also gives you quick access to your address book while writing emails.
Adding contacts to Thunderbird is straightforward once you know where to look. With your address book organized, you'll save time when sending emails and have all your important contact information in one place.
