All browsers have a download center, but it is not yet possible to manage them in every detail. Perhaps this is one of the reasons why many prefer to download via torrent clients since the options for direct downloads are still very limited. So we have a great tip for you: the app Leech, created by Many Tricks.
Recently updated to version 3.0, Leech is a very simple and lightweight tool that helps you manage your downloads. Among the most highly rated options are possibility to limit or speed up the bandwidth (depending on the server), schedule downloads (when to stop and when to start), manage multiple downloads, among others. To use it, just copy and paste (or drag) the download URL to Leech or the option that appears when you right click on Safari.
