This is a placeholder for a replacement class (CI_Log) that enables logging to FirePHP as well as firebug. To use it, just add my class to app/libraries and upload FirePHP.class.php to app/libraries/FirePHPCore. This means that the controller does not need to extend another class etc.
The FirePHP class can be referenced from the controller by $this->fire eg. $this->fire->log('Testing ...');
Anything logged with the CI_Log (and log_message() ), depending on the logging setting specified in the config, will also be logged to the console :)
