CompactHeader Publisher's description
Add symbol in header plane to switch between compact and expanded view
Thunderbird does not anymore have the ability to reduce the display size of header planel to one line starting with beta 3.
This addon adds a symbol to compact and expand the message header plane. The compact view can be set to either a one or two lines version.
A customization dialog can be opened for the toolbar in the header pane to change the displayed buttons and their style. (Do not install this add-on at the same time as the CustomizeHeaderToolbar add-on (https://addons.mozilla.org/thunderbird/addon/45601))
The shortcut "SHIFT+h" can be used to toggle between expanded and compact header view.
CompactHeader is a Thunderbird add-on that integrates the functionality of "RSS Linkify Subject" by Alex Dedul (https://addons.mozilla.org/en-US/thunderbird/addon/1704).
There is also an option to display only the email addresses in the compact header view.
