How to apply themes in mozilla 0.7?

[Thomas Scheffler]

Hi there,

I'm using mozilla 7.0 that build with svg and the one without it. The
problem is in both of them. Since version 0.7 there is no apply button
anymore when I select a new theme. So I thought clicking OK will result the
same. Nope. It doesn't.
Can anybody tell me how to apply a new theme then? How has the same problem?

Thanks
