Downloads are not accepted immediately, so files such as example.exe example.exe.part are always created in the original firefox download directory

It works, to download at least. PROBLEM: When I close the terminal window, after the download is done, the file disappears from the destination folder! I have to manually copy and paste each downloaded file before closing the terminal window, because of the original file always disappearing! FlashGot works with Wget without this issue, just it's not compatible with Firefox 57 unfortunately, so I might have to install an older version of Firefox over this.
