## Overview

Thunderbird is a free and open source email, newsfeed, chat, and calendaring client, that’s easy to set up and customize. One of the core principles of Thunderbird is the use and promotion of open standards - this focus is a rejection of our world of closed platforms and services that can’t communicate with each other. We want our users to have freedom and choice in how they communicate.

## Windows

### What the installer does

## macOS

### What the installer does
- Delivered as a disk image (.dmg) for Apple silicon and Intel.
- Installs the app `Thunderbird.app` into the Applications folder.
- The app updates itself, so it may be newer than the version Homebrew lists.
- On uninstall, Homebrew asks the app to quit.
- A full “zap” removal also deletes up to 8 support, cache and preference locations in your home folder.

### Versions (newest first) — Homebrew lists only the current release
