I'll debug it and preview again in Firefox. I built it fast and didn't properly test it before moving on to other work. When I do "real" work I do test in Firefox on all platforms.
Yea no problem! The product itself looks awesome btw.
The problem is your screen's resolution. I see the same thing in Chrome on OSX. Make your window narrower and all the text moves above the laptop.
Disable your Firefox extensions/add-ons/custom-css and try it again.
I only have firebug installed and am also using ff 23.0 (in reference to another comment), still skewed (even with firebug disabled).
