How to change server name on WordPress Installation?

You should be able to just add your port 8888 under general settings wordpress/site url, or directly in your config.php. In your case that would be http://localhost:8888 . I don’t know how or what browseling is but a quick glance also shows they support ssh reverse tunnel proxy for localhost, which is another option.
