works great!
you must download this extension first for editing some config on firefox

another tweak
Use error pages instead of dialog messagesBy default, Firefox displays annoying error messages if a connection fails, instead of quietly displaying the error information in the browser window as Internet Explorer does. To turn off the error messages and use pages instead, add the following code to your
user.js file: copy this
user_pref("browser.xul.error_pages.enabled", true);
cheers!
