Seems only Chrome exists as a browser. All others need not apply.
I rely pretty heavily on the box model for layout, but if you look at the CSS I included almost every browser extension (even Opera)
You can't see what's happening and the box seems to be improperly sized and spaced as well as problems with the terminal-style text editing window. The text flows off the bottom and cursor is misaligned: http://imm.io/WxrS
