Toggle Headers Thunderbird Extension

This extensions allows you to switch between the normal header view and viewing all headers when viewing a message by using a keyboard shortcut. The shortcut is Ctrl+H (single key shortcuts are unfortunately not allowed anymore). Prior to version 3 the shortcut is just H.

The extension is published at: https://addons.thunderbird.net/thunderbird/addon/toggle-headers/

Acknowledgement: The original idea for this extensions is taken from "Headers Toggle" by Pontus Freyhult which unfortunately was not continued for current Thunderbird versions.
