Still on an older version of Thunderbird and looking to upgrade? Luckily, the process to upgrade is fairly straight-forward.

Before we begin

During a version upgrade, some versions of Thunderbird perform data and other conversions (for example address book data) to enable new capabilities. If you skip an important version, then Thunderbird may not work, you may have missing or incorrect data, or other complications may occur. To avoid this, closely follow these directions.

During this process, third-party add-ons may require an update, or may no longer work on newer versions of Thunderbird.

Check which version of Thunderbird you currently have installed using Find what version of Thunderbird you are using.

Automatic upgrade with 60.9.1 or newer

You need to be on version 60.9.1 or newer to be able to automatically upgrade to the current version of Thunderbird.

Automatically upgrade to the current version

You can automatically upgrade in multiple steps from the version you start with (60.9.1 or newer) to the current version. The number of steps varies depending on where you start. If you start at 60.9.1, you will go from 60.9.1 to 68.12.1 to 78.14 to 91.13 to 102.15.1 to the current version (TB 115 or newer).

Repeat the following steps until you are at the current version of Thunderbird:

• Click ≡ > Help > About Thunderbird (About Mozilla Thunderbird in TB60)
• Click Restart Thunderbird ({Restart to update Thunderbird in TB60)
• Wait for the newly upgraded Thunderbird to open

And that is it, you have now upgraded to the latest version of Thunderbird! The interface may have changed from your previous version. We recommend familiarizing yourself with any interface changes.

If you are on a version older than 60
