downloaded files are invisible on desktop
For context, anything I download goes straight to my desktop rather than my downloads folder. Personal preference.
Every once in a while, when I download a PDF, it will 100% "download" onto my computer–meaning it's visible from my browser's download history and shows up in said download history as being on my desktop. However, the icon is grayed out within the downloads menu in my browser, and the file itself is not visible on my desktop at all. This seems to happen to some (but not all) PDFs I download from places like JSTOR.
How do I fix this? I'm getting quite annoyed. Not to mention, I'd like to delete any extra downloads that are just taking up space at this point.
