Previewing “rubber” layouts in Firefox Nightly

You can see how the site looks on screens of any width, simply dragging the edge of the page or specifying the exact size in pixels.



Over the weekend, Responsive Mode appeared in a fresh build of Firefox Nightly, on a stable channel it will be in Firefox 15.
