If you need to download something as large as 500MB, you’ll need to use a IDM, also known as Internet Download Manager. Download Accelerator Plus used to be my favorite, it was fast, stable and free. The only problem I had with the IDM is the adware and annoying pop-ups.
DownThemAll (DTA) is a download manager/accelerator extension for Mozilla Firefox, licensed under the GPL. It can pause and restart supporting downloads at any time, without losing data, and enables users to download all the links, images or embedded object contained in a webpage. What I like about DTA are:
- No Adware, Pop-ups or banners
- Runs on Mozilla Firefox
- Works across multiple OS – Windows, Ubuntu and Mac OSX

DownThemAll (or just dTa) is a powerful yet easy-to-use Mozilla Firefox extension that adds new advanced download capabilities to your browser. DownThemAll lets you download all the links or images contained in a webpage and much more: you can refine your downloads by fully customizable criteria to get only what you really want.
DTA can download the entire webpage, except for flash flv in YouTube. According to them, you are able to increase your download speed up to 400%, it features a smart download technique called ‘multipart download’. It splits files into multiple sections, which are downloaded simultaneously. Something like torrents.
I guess the most important feature of all is the pause and download function. Currently I am a happy user of DTA. For those using Microsoft Internet Explorer, here is a free download manager.
