mozilla firefox and cookies
 

i looked into the cookies control manager and i wonder if I can set a rule like this "block ALL coockies EXCEPT ones that are in the exception list", i can't find the way of doing this, i've to deny manually every site i visit :-(
plz help

go to Tools->Options. Open the "Privacy" tab and expand the "Cookies" options. Untick "Enable Cookies". Then click the "Exceptions" button and enter the domains you wish to allow. Make sure you click the "Allow" button instead of the "Deny" one.
