quick fix to make it readable on firefox, I right-clicked on the paragraph -> Inspect Element, selected the div.single-content and removed the "float:left" CSS rule.
You can also make the large Google screenshot smaller if you use the Image Zoom plugin (or know how to change it using Firebug or the default dev tools). I believe that is what's causing the layout to freak out.
You might have more luck getting the developer to fix it by providing some information about your browser. It works fine in the latest stable Chrome on Mac OS X, for example.
