I hate how now the Downloads menu is intermingled with History and Bookmarks. Firefox doesn't even display more than 4 attributes of each download: Name, size, website, and time. There is large amounts of wasted space, along with the sidebar of the Library menu. And if you scale this menu for Downloads, suddenly History and Bookmarks are a pain because you have to put it back. I liked having a small window I could look at if I needed. This really makes no sense to me - I just don't get why it'd go there.
