The Thunderbird application allows users to privately integrate and manage their online communications.
The Thunderbird Desktop, Thunderbird for Android, and K-9 Mail applications (together, “Thunderbird”) allow users to privately integrate and manage their online communications. K-9 Mail is a variant of Thunderbird for Android. All references to “Thunderbird” or “Thunderbird for Android” apply equally to K-9 Mail.
