Deleting of expired cookies

[ivan1]

It should be normal behavior for browser to delete expired cookies at idle time, and chrome does this but firefox does not. You need to manually delete all cookies after some time to make sure expired ones are gone and relogin and whatever else thats stored in cookies. Problem with this is site data is treated as cookies and some websites by design generate a lot of data in profile/storage/website+name folders and absence of cleanup algorythm causes folder to grow without control.
currently i have 6GB of site data and there is not even an option to clean it on exit like cache because cookies and site data are same checkbox.

As cookies and site data are unified now i searched on how to delete cookies selectively, but in fact clearing site data is what i needed in the first place. Turns out it was possible just untill recently untill history menu was dumbed down and settings merged into one. Bring back old history menu!!

clearing expired cookies should be implemented as well but is probably not as URGENT as bringing back old history menu that does not merge cookies and site data

// we're over both size and age limits by 10%; time to purge the table!
// do this by:
// 1) removing expired cookies;
// 2) evicting the balance of old cookies until we reach the size limit.
// note that the mCookieOldestTime indicator can be pessimistic - if
// it's older than the actual oldest cookie, we'll just purge more
// eagerly.
