Advanced Save Folder 0.9.1 is an experimental add-on for Firefox that enables you to specify a folder for your downloads based on the file extension or source website. For example, if you want to move your downloaded .mov files in to a specific folder, you can set this up. Alternatively, you can force all downloads from a particular website to download to a unique folder.
