Rated 5 out of 5 stars
Works just fine. I organize my emails by editing the subject line and really needed an add-on like this. The Header-lite editor no longer works this is a good replacement. Once in a while I have to right-click a second time on the email to get it to work, but otherwise its perfect. Thanks for the time it takes to code this. (Ubuntu Linux 20.04.2)This review is for a previous version of the add-on (4.3).
