Rated 4 out of 5 stars
Great add-on. Unfortunately, it doesn't play well with PrefBar (http://addons.mozilla.org/en-US/firefox/addon/67148). After I've installed Firemacs, the Prefbar Buttons are gone. I've no idea which of the two extensions is to blame for this, though.This review is for a previous version of the add-on (3.8).
