ThunderBird add-on implements RFC 2369 in displaying mailing list headers. It helps to view mailing lists in ThunderBird by providing easy access to information such as list name, owner, and email addresses in a structured manner.
With extended header view, you can simply click the links to access important mailing list options like archives, help requests, and unsubscribe functions. However, it's important to note that this extension requires Enigmail OR Mnenhy for it to work effectively. This is because the plugin has been optimized to get and parse special mailing list headers from messages, a task that's quite complicated to achieve in current versions of Thunderbird.
Overall, the Display Mailing List Header for ThunderBird extension is an excellent add-on for every Thunderbird user who wants to enjoy the full benefits of RFC 2369 in their email communications. Just make sure you're running Thunderbird version 1.0 and above to use this plugin.
