Handle ymsgr links in Firefox on Ubuntu

On Ubuntu, Pidgin is the deault messenger client and Firefox the default browser. A URL-handler for ymsgr exits and is set to purple-url-handler. So for example in Firefox, when you click on a link, like say ymsgr:SendIM?SomEtestY4H00Acc0unt, this should open up a window in Purple. However purple-url-handler is provided by libpurple-bin and this package is not installed by default. So to get this working, you will need to get this package installed. So if you want to Firefox to handle the ymsgr links and open up a window, please get this package installed.

And in the process of writing this post, I see that this configured using gconf2. And here is the specific command that provides this info

$ gconftool-2 --get /desktop/gnome/url-handlers/ymsgr/command
purple-url-handler "%s"

I thought this was earlier configured under Firefox by defining the following preferences.

network.protocol-handler.external.ymsgr = true
network.protocol-handler.app.ymsgr = "gaim-remote uri %s"

PS: I did not want to give my Yahoo ID there in the link above and get spammed with messages. So I have given a dummy ID that might or might not exit.
