Steps to Reproduce

	<slider mold="knob"
			minpos="0.0" maxpos="100.0"
			curpos="100" step="1" width="300px" angleArc="360"
			style="border: 1px solid black;" strokeWidth="120"/>

Current Result

FF renders the default up/down arrows for input elements with type="number" - breaking the visual appearance, cutting off the number

Expected Result

hide the arrows

Debug Info

this issue happens in FF (all themes excepted iceblue)

Workaround

add a style:

	.z-slider-input[type=number] {
		-moz-appearance: textfield;
	}
