Progressive Downloader Extension od Maxim Trushin

What this extension does:
1. Adds a new option to the right-click menu for links. When you right-click a link, you’ll see an option to download it using Progressive Downloader.
2. Automatically takes over downloads for certain file types you’ve set up before, so they continue in Progressive Downloader instead of your browser. For more details, visit: http://www.macpsd.net/?page=integration
