In development for the past several months, the Mozilla Thunderbird 60 release is a major one adding numerous new features and improvements, including new Light and Dark themes, OAuth2 authentication support for Yahoo and AOL accounts, individual update interval for RSS feeds, and support for WebExtension themes. Attachments handling during email compose has been greatly improved in Mozilla Thunderbird 60, which adds a new “Delete” button in the To/Cc/Bcc selector when writing emails to allow you to remove a recipient. Also, users can now re-order attachments using drag and drop, keyboard shortcuts, or a dialog.
