Download torrents with your Firefox

What? Download a torrent files with Firefox browser?'s true. Don't you believe me? Ok, please download this Wyzo/FireTorrent. It's an extension for Firefox. I have a friend who already installed it in his machine and download some of .torrent files but unfortunately its really slow down the Internet connection. And I don't have any idea how this guy can reach download speed nearly 100kbps. Weird..

Feel free to drop a comment if you have any experience using this extension. I really appreciate it..
