I just found out that MozBug 24998 (background images spill beyond rounded borders / -moz-border-radius) was fixed late last year. Nice!
Here’s a screenshot of a quick demo - it uses HTML but the same can be done in XUL. See how the corners of the background image don’t show through the edges of the porthole like before?

SubscribeThat back button looks stupid.
Cool to see that fixed
Not to pee on your bonfire or anything but this doesn’t work on Firefox mac (2.0.0.13)
@matt
Try it in Firefox 3 or a recent Songbird build.
Cool. Works for me with FF3 on Mac
