in the drop down box where it says remember history change to "use custom settings"
then go accept third party cookies "never"
This has nothing to do with your problem btw, you should just do it. (very occasionally a site won't work properly and if its a financial one you can check if it needs 3rd party cookies, otherwise fuck them)
For your problem you could try going to show cookies then remove all google ones. And then just ignore the privacy box forever.
Also make a habit of clearing cookies from sites like google - they just want to know everything about you so they can sell it to someone.
Done.
Fuck them.
BTW- What is a financial site?
