Changes in Thunderbird 78.6.0

browserAction

  • The :ref:`browserAction.setLabel` and :ref:`browserAction.getLabel` functions have been added. It is now possible to set a label value different from the title (which is used as tooltip text). The label can be set to an empty string to make the action button not have a label at all. If the toolbar is set to text-mode only (no icons), the action button label uses the title as fallback, in case an empty label has been set.

composeAction

  • The :ref:`composeAction.setLabel` and :ref:`composeAction.getLabel` functions have been added. It is now possible to set a label value different from the title (which is used as tooltip text). The label can be set to an empty string to make the action button not have a label at all. If the toolbar is set to text-mode only (no icons), the action button label uses the title as fallback, in case an empty label has been set.

menus

  • The standard properties available to :ref:`onShown <menus.onShown>` are now available for messages being composed, if your extension has the compose permission.

messageDisplayAction

  • The :ref:`messageDisplayAction.setLabel` and :ref:`messageDisplayAction.getLabel` functions have been added. It is now possible to set a label value different from the title (which is used as tooltip text). The label can be set to an empty string to make the action button not have a label at all. If the toolbar is set to text-mode only (no icons), the action button label uses the title as fallback, in case an empty label has been set.
