FIREFOX Download Path

I have a recurrent problem related to Download path with Firefox (and maybe Flatseals - another Flatpak app that is used to give permissions to apps), here is my problem:

I would like Firefox (Flatpak) to REMEMBER the LAST path everytime I download a file (for example: several pictures in a row)
Today, when I’m doing that, Firefox is asking everytime where (Download path) I want to download the file, which is a big waste of time and very unconvenient !
Any help would be very appreciated. Thanks a lot GNU Linux friends !
