SVG not working in Firefox, error or bug?

Question

Mozilla Firefox

A separate HTML file is loaded on the site, in which one large SVG sprite is declared.

On the ground I use the usual call.

<svg width="48" height="48">
  <use xlink:href='#Leaf'/>
</svg>

Everything works in Chrome and IE, not in Firefox.
