I think the large box that appears in the top left of our screen every time we adjust sound is ridiculous! It takes up so much space and stays on long enough that I have to sit and wait for it to disappear before doing something that is underneath it. I can't believe that Firefox would be continuing to use such a large version of this after no doubt negative feedback and a too techie way to get rid of it. It seems to me that there ought to be a choice for us as to whether we want this gigantic version or of much small version, or the third choice of not having it at all, adjustable through settings. In this day and age it's unbelievable such a dinosaur is part of your features.
