Rejy, for the record, I've downloaded many ISOs and other large files using my browser (Chrome) for many years. While years ago it was problematic to use the browser to download large files, it seems to me that that is not so these days. Of course if you have a very slow or bad connection, it may not work, and this is where download tools come into their own. But I think that for most people, browsers will work OK. The real advantage of the download tools is that a transfer is usually restartable and that is not always possible with a browser download.
