Registering the ssh protocol

You need to tell Firefox which program it should use for that particular protocol.

Linux, Mac OS:

Firefox gets its protocol information from its hidden settings.

1. In the Location bar, type about:config, and press Enter/Return.

   * The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise!, to continue to the about:config page.

2. Right-click Hold down the Ctrl key while you click anywhere in the grid, choose New, then String.
3. In the Enter the preference name prompt, type in:
   network.protocol-handler.app.<my protocol>
   (replacing myprotocol with the protocol you want to register) and press OK.
4. In the Enter string value prompt, type the path to the program you want the protocol to start and press OK.

Now that the protocol has been registered, try the link again. You may get an External Protocol Request dialog. Click Launch Application. The program you chose should now start.

* Still not working? Make sure that the path you put in the preference is correct. Due to a bug in Firefox, entering an incorrect path will give you the same error message.

Here's the protocol for ssh:

Preference Name:	network.protocol-handler.app.ssh
Value:			/usr/bin/nautilus
