Notice: You may experience problems when using FirePHP through proxies (ie. Nginx, Varnish, etc.), as it requires high HTTP headers size limit in order to work. Result may occur as 502 Bad gateway error code. Try manipulating parameters on this plugin settings page (admin/plugin_settings/fire_php) in order to limit amount of data transmitted.
