Created attachment 749357 [details] zoomed input type range element in opera When zooming on a page, <input type="range"> element does not really change in size. It only becomes longer. I'm not sure it's the prefered behaviour as zooming should make it easier to click (bigger draggable area..). For reference, I included an image of what opera shows when zooming on a page with an <input type="range">. It's not beautiful, but it's more accessible I think.
I think the reason is because we don't use em height on horizontal themed range. You should try with <input style="-moz-appearance: none;" type='range'>.

You should try with <input style="-moz-appearance: none;" > type='range'>. It's actually more related with the way the widget is drawn. It should be using DrawCellWithSnapping instead of calling directly HIThemeDrawTrack. The patch in bug 872085 would likely solve this one too.
