Confirming this bug.

I opt this bug to be raised as important because all XUL apps using groupboxes running on Firefox-3 will look very ugly, and in some cases confusing because the grouping intention is not apparent. This includes Firefox's Preferences dialog.

I have tried a couple of style hacks (border, padding, background, etc.) with no luck.
