I really want to give this more stars but I can't. I have have two major complaints about FDM. First, a bit minor, is that this extension needs a way of either bringing the download manager to the forefront, or at least a notification that your download has began. Second, and is a major for myself, is that the extension completely bugs out comments with youtube for some reason. If you use youtube and comment/reply regularly, you'll find yourself disabling this extension to prevent comments from posting duplicates.
