@slowfallinward I'm pretty sure this autohide has been a feature for a long time. (And it makes sense, you generally only want the downloads list when you download something.) As for weird shit, that's the generic browser behaviour, when
encountering a file it will display it if it knows how, or try to download it otherwise. Chrome does the same, displays the PDF, webm, image, whatever, with an option to download it instead of presenting a download dialogue immediately .
