I have this issue too, and I figured out a workaround. Deleting the files manually via rm frees up space. Deleting files via qBittorrent via UI or automatically does not.

Turns out the files were just being moved to a “.Trash-UID” (where UID is the UID of the container) folder in the /downloads directory (or wherever that folder is mapped to on your host). Clearing that out freed up the space.

I suspect this is a bug where the “Delete files permanently” setting is not being respected. You might want to set up a cron job to delete that folder periodically in the meantime.

Now that Google isn’t allowed to pay them default search engine money, I think this was expected.

Ideologically I think it’s a good thing the US government is challenging Google’s monopolistic practices. Unfortunately, that money was a massive percentage of Mozilla’s income.

It really was short-sighted of them to put so many eggs into one basket.
