Joyful!! Rated 4 out of 5 stars

Only a little issue on XP SP3, FFox3: the titles on the tabs bar are not well adjusted to the title-space.

But it's a plenty of joy theme! :-)

This review is for a previous version of the add-on (4.0.21.03.11). 

Thanks for the review.Firefox 3 is no longer supported.I moved to Firefox 4.There are few more things which I have to fix but this is going to happen sometimes in the near future.
