User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:19.0) Gecko/20100101 Firefox/19.0 Build ID: 20130215130331 Steps to reproduce: Drag an image with an opacity set to anything lower than 1. <img src='image.jpg' style='opacity:0.1'/> <img src='image.jpg' style='opacity:1'/> Actual results: The ghost image that appears when dragging has the same opacity as that of the image, making it potentially invisible. Expected results: Ghost images should always appear at full opacity. Chrome does this, its ghost images have full opacity regardless of image opacity making it clear when images are dragged to the desktop, even when they have 0 opacity. The 0 opacity dragging allows for 'drag to save' implementations that would otherwise be impossible, that's how I ran into this problem.

We should differentiate between the behavior of the content and of the browser chrome. The chrome should be able to do whatever it wants with ghost images (transparent, opaque or anything in between), while it does make sense to have ghosting by default when dragging images from inside a web page (as you are not actually moving, but just copying stuff, and that copy doesn't get real until you drop it).
