Review for Message Header Toolbar Customize by Brad
Rated 4 out of 5 stars
This is a great add-on. Thank you so much! I dropped one star because it's not possible to manage the "Mark As" toggle button. Right now, "Mark As" can only be reached under "More" and is not in the list of buttons that can be managed.
This review is for a previous version of the add-on (2.1.1).To create your own collections, you must have a Mozilla Add-ons account.
