How can I delete downloads in Firefox? I have downloaded two PDFs that I no longer wish to keep, I have going to Firefox menu, downloads, found the files, and have tried long pressing them, right swiping them and pretty much anything else oh, and there never seems to be a menu or option to delete them.

I have read other similar questions that simply state that you have to long press and then select Elite, but long-pressing only creates a system feedback like a beep or vibrate but no menu pops up.
