While in the past you could choose ANY folder in your PC as download folder for this app, since a while it forces you to choose either the default Windows Downloads folder or a subfolder of it.
And contrarily to the past, it also COMPLETELY bypasses the Firefox setting to "ask every time", i.e. even if you have this option active in the Firefox settings, while you use this app there is no popup to choose where to download.
There's the option "Download as" but that too, the lazy dev didn't even noticed that there's a but that lets the download start immediately without any popup. You have to stop the download and there it opens the popup.
MENTAL!!!

For me 10001% USELESS as of now, and I VERY DEEPLY resent the dev for this. SHAME ON YOU!!!
