I checked tabs behaviour on Firefox 38.0.1 Final Portable and it's the same.
I don't insist on that this is a ColorfulTabs' bug, maybe for some people this is a useful feature for dragging fullscreen window, therefore I ask you to add the option something like "Default Firefox behaviour for choosing tabs" in extension's settings.
