After automatic update to 32.2 (then I tried to update to 33.0 beta with no improvement) Firefox keeps returning a "Gone The requested resource /administrator/index.php is no longer available" reponse when trying to access joomla login. The problem is there even when I fill manually the fileds "user" and "password" in the joomla admin login page. The problem appears in different sites on different servers, and do not occurr using Google Chrome. It's clearly a Firefox issue. Could you please give me some ideas on how to solve ?
