Rather to develop my own js window console to display parameters and some usefull infos, by using for instance the debug classes from ditto, I think to use the plugin
FirePhp to log traces in Firebug windows.
Is make it sense ? (even if It will be limited to Firefox). And if not what are the advices regarding this topic (addon debug console) ?
My goal is to log the user parameters and sql statements.
And is somebody has already use FirePhp ?
[EDIT:
the firePhp core library seems integrated in the core of Drupal]
[EDIT: require Php5]
