-/* We are registering protocol handlers for news, mailto and irc
-   because mozilla load all modules on startup, so if you have these
-   components installed it will try to use them as protocol handlers.
-   Our implementation just forward to external protocol service.
-   Ftp is a special case, it can be handled by mozilla but we
-   want to use an external client when one is configured in GNOME
-   handlers.
-   IMPORTANT: there is no need to register handlers for other protocols
-   here. Once they are configured in GNOME, they will just work.
