Using Self-destructing cookies add-on I have Firefox set to remove all cookies on exit/ close: Custom settings for history unchecked: always use...remember my brow...remember search... Accept cookies from sites (with an exception list that works correctly) Accept third-party cookies: never Keep until: I close Firefox Settings: all checked to clear except site preferences.

I had been noticing a very long list 50-100 cookies identified by CC Cleaner as being on my system that Firefox dis not display. So I began using the Self-destructing cookies add on. The app definitively shortened the list.

However, cookies still remain after closing -- per CC cleaner. Some are api.websitename.com others appear to be flash cookies.

Why are they not being removed? Thank you.

They could be cookies auto-generated when Firefox first starts up. Or cookies generated by your add-ons. So they necessarily do not belong to the webpages but the browser itself.

Thank you for your time and courtesy of a reply. I believe you are correct or perhaps they are "session" cookies used to restore Firefox after a crash.

You may have installed an extension that maintains a set of special OPT-OUT cookies if you can't remove some cookies permanently.

In that case you need to uninstall the extension to remove those opt-out cookies.
