Whenever a file larger than a .jpg finishes downloading, a little box pops up in the corner of the screen that says "All downloads have completed." It's distracting. The download arrow in the corner already lets me know, *plus* the new download progress bar in the dock icon. I do not need three different things telling me when a download's done. Also, the box vanishes just quickly enough that I can never manage to get my mouse into position to right-click on it for any information about it. This box has only started popping up since updating to Firefox 22.0.
