Tor Browser confinement allows downloading to /tmp

By settings the path (e.g. /tmp/file) it’s possible to download files from Tor Browser to /tmp directory. It’s expected because our torbrowser profile loads the gnome abstraction, that itself loads the user-tmp one. Do we want that? Can we do differently without breaking the browser?
