Downloaded images from firefox not showing up in MyFiles

I can download imafes from twitter or from texts and they are in the gallery, but when i dl an image from firefox, it never shows up in either MyFiles or the gallery. They do not appear in the downloads file. It does appear as a notification with DownloadManager at the top, but when i click on the image file name, it says no location specified.

Try the 3 dot menu (upper right)/Tools/Downloads.
