Thunderbird 139 has been released, introducing notable features such as ‘Mark as Read’ and ‘Delete’ actions directly accessible from email notifications. This update also integrates enterprise policy options, granting users more granular control over in-app notifications.
In addition to these new actions, Thunderbird 139 allows users to manually sort folders in the folder pane and customize the row count for Cards View through the Appearance settings. The update addresses various bugs, including those related to message composition, OAuth links, attachment retrieval from UNC hosts, and folder sorting. It ensures that folders removed from Favorites behave correctly and also resolves issues with message headers not displaying correctly in specific views.
The new release enhances usability by refreshing selected folders when applying Threading settings and fixing crashes related to message copying. Importantly, this version also resolves critical security issues, enhancing overall application safety.
