Firefox 3 - Adding magnet: protocol

[whetphish]

Hi,

I am running Firefox 3 on Gnome 2 under FreeBSD 7.2-RELEASE.

Basically I am trying to get Firefox to open Vuze when I click on a magnet: link, but at the moment I get the following message:

Firefox doesn't know how to open this address, because the protocol (magnet) isn't associated with any program.

I read a guide which suggested adding/setting the following in about:config

network.protocol-handler.app.magnet String -> /usr/local/bin/vuze
network.protocol-handler.handler.external.magnet Boolean -> true
network.protocol-handler.expose-all Boolean -> true

With these settings I get exactly the same error message clicking a link.

Another guide suggests adding the following in gconf-editor ...

/desktop/gnome/url-handlers/magnet /desktop/gnome/url-handlers/magnet/enabled Container
/desktop/gnome/url-handlers/magnet/command String -> /usr/local/bin/vuze %s
/desktop/gnome/url-handlers/magnet/enabled Boolean -> true
/desktop/gnome/url-handlers/magnet/needs_terminal Boolean -> false

This doesn't work either and has no effect on the error.

Note that I managed to create the string network.protocol-handler.app.irc in about:config in Firefox and set it to /usr/local/bin/xchat. This runs xchat fine when an irc: link is clicked.

As always any help would be greatly appreciated. I can't work out why this works for the irc: protocol and not for the magnet: one.

Thanks in advance,
whetphish.

Just a quick update - a few threads I found on different forums seem to indicate that Firefox no longer lets you add your own protocols and instead relies on the underlying OS/environment to provide them. It appears to completely ignore the Gnome settings in /desktop/gnome/url-handlers as the man: and info: protocols configured there don't work in Firefox. I looked at this page which explains how to add MIME types in Gnome 2.8, but doesn't mention adding protocols.

Does anyone know how I can add protocols in Gnome 2.8?! I've googled but can't seem to find any information.
