Have they read it?

For the life of me, I can't find where Thunderbird keeps track of whether or not an email I've sent has been read. Yes, I get read receipts, but I remember in Outlook, I could check to see who read a particular message. Is this available in Thunderbird? And if not, is there an add-on that does it? The one Mozilla suggests is way old, and won't work with the current version. Thanks.
