Configuring Firefox to use Transmission for Magnet links in GNOME:

1. gconftool-2 -t string -s /desktop/gnome/url-handlers/magnet/command "/usr/bin/transmission '%s'"
2. gconftool-2 -t bool -s /desktop/gnome/url-handlers/magnet/needs_terminal false
3. gconftool-2 -t bool -s /desktop/gnome/url-handlers/magnet/enabled true

When you start Transmission's GTK+ client version 1.80 or newer, it will make these three calls for you if you don't already have a magnet handler set up.
