I often find myself gathering lots of files over time from a given website, which I then keep in a given subdirectory of an eventually complex directory structure. I have a "Downloads" folder where goes everything I download and I end up repeating the same movements of files, as soon as they're downloaded, and my Downloads folder becomes slowly a heavy mess. While one folder would still be the go-to for Downloads, would it be possible to add a layer of other default Downloads folder, based on the domain the file is coming from, and maybe even subdomains and precise URLs? It doesn't seem this is a current Firefox feature and I didn't find a proper extensions among all the Download Manager ones. This could be managed where you currently choose the only folder for all Downloads, as well as in the pop-up where you choose to only download the file or execute it with some software.
