I recently tried applying a gradient background to a webpage using only CSS3.
while testing out the following code:

```
body {background: -moz-linear-gradient(top, blue, white);}

```

The result was:
![firefox grads went wrong](https://i.stack.imgur.com/4xPdX.jpg)

Not exactly what I was looking for...
Any idea what is going on?
OS is Win7 64bit and Firefox 4.
Thanks!
