Rated 5 out of 5 stars

Works really well for me. But is it going to be updated to work with Thunderbird 68, I wonder?

Great to hear from the developer that he will be updating this add-on. Thank you very much in advance.

Hello wilf21 - Thank you for your review and rating. Yes, I will be updating the add-on to TB 68+ - https://github.com/jeevatkm/ReplyWithHeaderMozilla/issues/88
