After the latest Thunderbird update, I was frustrated to find my old compact headers extension no longer active. I should be used to updates that break perfectly functional things by now. But it boggles the mind why Thunderbird can't implement a simple header toggle. This developer has brought functionality back to this program with this add-on. And he was great with answering concerns I had about the blanket permissions requirement. I don't generally review things, but these add-ons truly do increase my work productivity, and I am grateful! Thanks!

This review is for a previous version of the add-on (2.16).
