The Thunderbird devs sometimes do wacky things, and destroying standards compliance for reply-all is one of them. I thought I was losing my mind when my reply-all headers started going wonky on me, and I finally figured out that it was T-bird that had gone crazy, not me. This add-on takes away the crazy, so many thanks!

Now if they would just fix the "mark all deleted messages as read" thing I would be happy ...
