Most of my folders don't even have an "Arrange by" option when saving photos in Firefox but one particular folder does. This folder has a lot of folders in it and I sort by date modified so I can see the last images saved, but with this "Arrange by" being present, which isn't present in any other folder, it puts the folders up at the top rather than the bottom.

How can I get rid of this "Arrange by" nonsense?

Update: I figured out why this folder is doing this. The directory linked to in the quick access is a "library" but there's no way to get it to be set to the actual location, every time I try to save it the end result just reverts to a libraries location. How can I prevent this?
