How to hide ajax requests from firebug console?

Please, call this function after ajax success or fail:

$('.result').load('testtemplateboth/testpagetpl');
clearconsole();

function clearconsole() { 
  console.log(window.console);
  if(window.console || window.console.firebug) {
   console.clear();
  }
}

OR

$('.log').ajaxComplete(function() { 
  clearconsole();
  $(this).text('Triggered ajaxComplete handler.');
});

function clearconsole() { 
  console.log(window.console);
  if(window.console || window.console.firebug) {
   console.clear();
  }
}
