Firefox 20, downloads
Until this am, FF always saved downloads in the selected folder /user/xxx/downloads. This folder still has all my previous downloads in, but if I download today I get an empty 'download' folder. I have reset the location several times, but if I now select 'Downloads' it takes me to a tree headed 'Library' and an empty folder (second down below 'History') titled Downloads. I cannot see anything relevant in the Mozilla profile. Where in about:config is the download location stored or where else do I look?
If I run as admin, FF still correctly shows downloaded items.
