Message Header Redesign

Thunderbird 102 helps you be more productive with less effort. When reading your email, the redesigned message header allows you to focus on what matters as it highlights important information. It’s also more responsive and easier to navigate. Plus, you can star important messages from the message header itself, and easily convert them into a calendar event or a task.

New Address Book

Thunderbird 102 gives your contacts a serious upgrade! The refreshed design makes it easier to navigate and interact with your contacts, and helps you better understand who you’re communicating with. The new Address Book has compatibility with vCard specs, meaning if your app can export your existing contacts into vCard format, Thunderbird can import them. Each contact card also acts as a launchpad for messaging, email, and event creation.

New Import/Export Wizard

Thunderbird 102 makes it quick and simple to move your accounts and data around. The new step-by-step wizard provides a guided experience for importing all that data that’s important to you. We’ve also taken extra precautions to ensure that no data is accidentally duplicated in your profile after an import. Moving from Outlook, SeaMonkey, or another Thunderbird installation is easier than ever. No add-ons required!

New Spaces Toolbar

Thunderbird 102 makes navigating the application more intuitive thanks to the new Spaces Toolbar. Move between all of your activities with ease, whether it’s managing email, working with contacts through the awesome new address book, using the calendar and tasks functionality, chat, and even add-ons! If you want to save screen real estate, the Spaces Toolbar can be dismissed, and you can instead navigate the different activities Thunderbird offers with the new Pinned Spaces tab.

New Matrix Chat Support

Thunderbird 102 offers a new way to chat privately and securely with your colleagues, friends, and family. We’ve added support for the open-source, decentralized chat protocol Matrix, and it’s usable right out of the box! (As always, we welcome your feedback since it’s an evolving service.)
