after that i updated black reponsive themes also to match new version of xenforo.
But looks like xenforo 1.5.2 have a bug when using firefox.
Styles cant update when when selecting styles in bottom of forum.
I think its a xenforo problem, and not the actuall style that does it.
fire fox it wont update , but Chrome works.
I tried deleting cookies deleting cache in firefox , noting helps.
