Rated 5 out of 5 stars

This is an awesome addon, I really love it. One small thing bothers me though: when I place tabs at the bottom I cannot select tabbar transparent background, is there a solution for this please?

This review is for a previous version of the add-on (1.4.7.1-signed). 

Thank you.
Curently, there is no possibility to choose tabbar transparent background with tabs at the bottom with Noia Fox Options. I will see this in a future release.
A solution : You can have tabbar transparent background and tabs at the bottom if you install the Tab Mix Plus add-on.
Tab Mix Plus options : Display - Tabbar - Position : bottom (below content). If you choose tabbar background transparent option in the Noia Fox Options, you will have what you want.
