Title: Fix for Firefox 8

https://developer.mozilla.org/en/CSS/background-size

Gradients are treated as images with no intrinsic dimensions or intrinsic proportion.
This behavior changed in Gecko 8.0 (Firefox 8.0 / Thunderbird 8.0 / SeaMonkey 2.5) . Before this, gradients were treated as images with no intrinsic dimensions, with an intrinsic proportion identical to that of the background positioning area.

This means that for gradients in Firefox 8, both width and height need to be given explicitly in background-size.
