Firefox keeps creating ~/Downloads on Linux

Hi. I am running Firefox 149.0.2 on Arch Linux (Linux 6.19.12-arch1-1 (x86_64)). I have configured Firefox to use the "~/downloads" folder for downloads instead of the default "~/Downloads". I have also checked the "Clear cookies and site data every time you close Firefox" box in the "Privacy & Security" tab of the settings page, and configured the History settings to "Never remember history". The Downloads folder I have set is indeed respected by Firefox: all files I download are saved to "~/downloads". However, every time I close Firefox it creates a folder entitled "Downloads" (with a capital "D") on my home folder. I do not want this folder to be created. This really looks like a bug from my perspective, but is there some way yo fix this via the "about:config" tab? Thanks for the attention.
