Rated 1 out of 5 stars

ColorfulTabs versions 12.3 -- 12.7 break Tab Mix Plus in Firefox.
ColorfulTabs & Tab Mix Plus are two of my "must have" extensions; I love 'em both (5 Stars each!), & heretofore they've gotten along very well. Unfortunately regardless of the build of FF I'm using (from 12 through the Nightlies), ColorfulTabs now:
1. Causes extra blank tab which can't be closed.
2. Causes "Close Tab Button" in tab bar to disappear.
3. Causes "Scroll Tabs Buttons" to appear in tab bar, even when there aren't enough tabs to scroll.
Tab Mix Plus works fine when ColorfulTabs is disabled.
Already tried with fresh FF profile, only these two extensions. Installed Tab Mix Plus first, it worked perfectly; added ColorfulTabs, above faults occurred.
Please fix this, so I can have my optimal FF experience again!

This review is for a previous version of the add-on (12.6.1-signed).
