Downloading files using the Firefox browser seems like a pretty straightforward process. You click a link, perhaps choose where to save the file, and wait for the file transfer to complete. However, you have more control over this process than you probably realize, as the browser offers the ability to customize various download-related settings in Firefox: changing the download location, displaying plugins, and more.
