any way to get the filename of a removed download listing? or find the deleted temp file?

so, hi, im using Firefox Quantum a download failed i right-clicked the entry on the download list, selected Go To Download Link (to re-download it) and removed the entry the problem is that Firefox didnt go to root.com/download but to root.com and now i dont have the correct download link is there a way to at least retrieve the filename of the download? is there a log or something? how does firefox delete the temporary files? i couldn't find anything in the recycle bin? would a file recovery software be of a any help? i was in private mode so there is no history of the link either thank you
