Compact Headers is an absolute must-have for Thunderbird! Seriously — Thunderbird should ship with this included.
By default, Thunderbird wastes a huge amount of valuable screen space on the header when viewing an email message. That makes it hard to use on a laptop. That huge header is usually useless.
Compact Headers is great. It does exactly what you need! With it, your email shows the smallest possible header with just "From" and "Subject". It has a small arrowhead you can click on to see the entire header on those rare occasions when you actually want to see it.
You might have to look hard to find the new version of Compact Headers that works with current Thunderbird.
