Unlike other web browsers firefox supports wide range of plugins. Which makes your life easier.Whenever I try to download torrent files it first downloads the torrent for the file then using any other software(utorrent, bittorrent, flashget etc.) it will download the actual files.
Instead of this you can download torrent files with a single click. All you have to do is download and install this plugin named FireTorrent. This plugin can be really useful for the torrent users. Using this you can easily download the files from torrents inside your firefox.
