Rated 3 out of 5 stars
Great product! I've been using it for years now. Only one problem, recently the last few updates after restarting my browser colorfultabs opens a tab in EVERY windows! How annoying! So I tried to tell the author about it on his website, only you need to register to comment and registration is disabled and there is no other way to contact the author! >:-( At least have your website working! So I am deducting a start for the error and another for the poor website experience.This review is for a previous version of the add-on (19.7.1-signed).
