Rated 2 out of 5 stars
Could it be, that this AddOn has a bug at least in then in the UI? The developer wrote, there should be 4 Tab's in the options, but there is n o n e.
And the 'support site' is simply something - sorry - which I can't identify as a homepage (and is reached after 2 redirects... why?). May be this is not the right place to file a bug, but the so called 'support page' is it less than ever.
Primarily I intended to rate it a 3 or even 4 (at least for the idea, even if it everything than new!), but even without a clear way to post bugs - it's not more to me than 2... and I uninstall it now and go on using >Colorful Tabs
