<title>Bug 1219985: Unsetting moz-opaque should clear the canvas even if the canvas has been created with alpha:false, and the canvas should stay opaque.</title>

<div style="width: 200px; height: 200px; background-color: red;">
<canvas id="c" width="200" height="200" moz-opaque="true"></canvas>
</div>

<script>

var c = document.getElementById('c');
var ctx = c.getContext('2d', { alpha: false });
ctx.fillStyle = 'green';
ctx.fillRect(50, 50, 100, 100);
c.removeAttribute("moz-opaque");
