DownThemAll! download manager for Firefox

I was having trouble downloading the ISO (disc image file) for Windows 7 Home Premium with Firefox. The 3.0 GB file always died around 200 MB, and I'd have to restart it. After this happened 4 times, I went in search of a better download manager. Google led me to the Firefox extension DownThemAll!

I installed the extension and restarted Firefox. I then right-clicked the ISO link in Firefox, and selected Save link with DownThemAll! I was able to pause and resume the download as necessary, and after a few hours (I have a slow DSL connection), the download finally completed!
