Previously I was using flashget as download manager which is 5.5mb in size, and it has built in torrent, which personally I don't quite like it. On top of that I had to use flashgot which is a firefox plugin to capture link from browser (oh yeah this is freakin useful for rapidshare links) and transfer it to flashget. Now I uninstalled both flashgot and flashget, getting an Orbit Downloader, which is just 2.2mb in size, and better.. it has built in firefox integration.
