Align widgets horizontal

Hello again.

I've placed both sidebars at the right of my site. I'd like to align 2 widget horizontal. I've made i trick. I've placed one text widget with <br> up from the one widget and i can see it correcty in Safari. But in FF its not.

Is there a way to do that right and no with tricks ?
