Unified Toolbar

For Thunderbird 115 Supernova and newer there is a “Unified Toolbar” on top of the Tabs Bar, which is fully screenreader and keyboard accessible.

This toolbar is used for all “Spaces”, which are Mail, Address Book, Calendar, Tasks, Chat and Settings. The toolbar is customizable by right clicking (control click on macOS) > Customize....

Customize... offers a common set of buttons available for all “Spaces”, which correspond to the Spaces Toolbar Introduced in 102. Also available are Spaces-specific buttons for each Space.

Full keyboard navigation includes Tab and arrow keys to navigate, Enter to add a button to the toolbar, Delete to remove it, and Alt with arrow keys to move buttons around on the toolbar, in addition to mouse actions such as drag and drop.

Please refer to the following screenshot:

• 1. To select a toolbar to customize, click on one of the buttons for the desired Space you wish to customize i.e. Mail, Address book, Calendar, etc.
