• Support for the HttpOnly cookie attribute, which marks the cookie as readable only at the request of the server and is not available for client scripts;
• a new option in the settings: “Warn me when web sites try to redirect or reload the page” (“Warn me when sites try to redirect or reload the page”), allowing you to inform the user when the meta-element HTTP-EQUIV=refresh present on the page HTTP-EQUIV=refresh ;
