The interface for adding attachments has also been adjusted. WeTransfer has been removed as the standard provider for FileLinks and the corresponding option in the drop-down menu has also been removed. The warning for large file attachments remains active.

New keyboard shortcuts for easier operation

Keyboard and shortcut enthusiasts in particular will be delighted with version 91 of Thunderbird. Because the update adds some practical shortcuts, especially when writing e-mails.

If you want to put someone in CC or BCC, you can now navigate to the corresponding address fields with the shortcuts Ctrl + Shift + C or Ctrl + Shift + B. To add files, the shortcut Ctrl + Shift + A is now sufficient instead of clicking the Attach button.

Built-in calendar is improved

The calendar is now a native part of Thunderbird. In version 91 there are numerous improvements. Particular focus was placed on the simple handling of appointments and tasks.

If you click on an appointment, the confusing editing mode no longer opens immediately, but a slim pop-up for viewing the appointment information, such as title, calendar, time and description. If you want to edit the appointment after all, you can do this using the edit button.

Extensions

Since the previous version, Thunderbird no longer supports the old extensions, but only relies on web extensions, which are called Thunderbird Mail Extensions. To make the change easier, Thunderbird now automatically suggests alternatives for discontinued and incompatible add-ons in version 91.
