I'm on firefox and it looks alright for me... Maybe they test it but it works for them. With the current version numbering schemes, there are many conditions to test.
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).
