Possible dupe of #1960? Unclear to me

If you want to use a custom profile you will have to specify it via the profile capability of moz:firefoxOptions. Only that way geckodriver will take care of the appropriate Marionette port. In your case it just passes the profile path to Firefox.

If you want to keep using this technique you will have to tell geckodriver the port Marionette is listening on, which can be controlled via the Firefox preference marionette.port.

Otherwise check issue #1058 for more details.
