Review based on Firefox version 16.0.2.
This skin has great visual appeal. However, my testing (by switching back and forth from the default Firefox skin) is that Shine Bright Aero 1.3.2 has a bug pertaining to pinned tabs. Once you've opened a few regular tabs, you will notice that clicking on a pinned tab will not select it, and therefore, all pinned tabs become inaccessible. If you close one, or maybe more tabs, the pinned tabs will become accessible again. Very annoying behavior. Renders the skin unusable, IMHO.
Also, unless you have tabs set to load immediately when Firefox starts rather than when selected, the tab background is oddly colored by a background area that does not batch the foreground tab shape. Looks horrible.
