Created attachment 660253 [details] firefoxTransparencyBug.html User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_4) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1 Steps to reproduce: I loaded a transparent image into a canvas. I then got the content as an "image/png" dataURL and rendered that to another canvas. See attached test case (alternatively https://gist.github.com/3703025). Actual results: The canvasses do not have the same content. Expected results: The canvasses should both be equal in terms of ImageData and resulting dataURL.
