Thunderbird 91 is available as a manual upgrade​

Thunderbird 91 is a new major version, which introduces new features and changes. The email client is the first to support Apple Silicon CPUs natively, which benefits Mac OS users.

The program makes use of multiple processes by default now, similarly to how Firefox introduced support for the feature a long time ago.

The email account setup process has been improved in the new version of Thunderbird. The email client supports CardDAV address books now, and will detect these automatically based on the email address the user provides. Similarly, remote calendars will be detected automatically to streamline the setup process.

If you set up a Gmail account, Thunderbird will detect the address book and calendar, if available, to suggest to import the data right away. [...]

Mozilla released Thunderbird 91.3 to fix several high-impact vulnerabilities that can cause a denial of service, spoof the origin, bypass security policies, and allow arbitrary code execution.
Triggering most of the newly discovered bugs requires a user to open a specially crafted website in a browsing context, so the exploitation is relatively simple.

Thunderbird users, who have add-ons installed, may notice that the email client will run checks for add-on updates automatically after updates now once Thunderbird 91.3.1 is installed on the device.

Extensions that are installed in Thunderbird are configured to check for updates automatically by default. Thunderbird users can disable this in the preferences.

The new update check after the installation of updates is designed to reduce the impact of Thunderbird updates on installed extensions. Sometimes, Thunderbird may introduce changes that may interfere with the running of extensions, unless these are updated.

How to configure Thunderbird to open emails in windows​

Here is how you configure Thunderbird to open emails in separate message windows or a single window.

1. Open the Thunderbird email client, if you have not already.
2. Select Tools > Preferences. Thunderbird may not display the menubar at the top by default. You can display it temporarily with a tap on the Alt-Key on the keyboard.
3. While the General tab is active, scroll down to the Reading & Display section.

There you find the preference "open messages in". It has four options, of which three determine how Thunderbird opens messages that you select:

• A new tab -- This is the default option; emails are loaded in tabs, with each email being loaded in its own tab. Tabs get reloaded when Thunderbird is started the next time, provided that it has not been closed before.
• A new message window -- Opens messages in their own window. Multiple windows are created, one for each email that you open this way.
• An existing message window -- Opens a maximum of one window for all emails. When you select a new email, the old is unloaded and the new message is displayed.

The fourth option determines how move or delete operations interfere with open emails. You can check the option -- close message window/tab on move or delete" to close tabs or message windows automatically if the loaded email is moved or deleted.

The changes that you make take effect immediately. Just select another option if you want to switch again or restore the default behavior of Thunderbird.
