Add-ons are usually created for specific needs such as removing cookies more quickly after you leave a site, or managing other aspects of cookie storage. Are they necessary? Not for me, but your needs might be different.

Firefox stores cookies in a database file named cookies.sqlite (all sites together in one file) in your profile folder. (Profiles - Where Firefox stores your bookmarks, passwords and other user data)

To check what is present at startup -- when cookies were supposed to be cleared at shutdown -- you can go to the Preferences page, Privacy & Security panel, Cookies and Site Data section, and click "Manage Data" to see the currently stored cookies and site data.

Are they HTML5 cookies? I use Bleachbit which refers to DOM storage. If you don't want to use Bleachbit to remove them, it can possibly tell you where they are on your system.

In the old days, the term Super Cookies was used to refer to Flash plugin LSOs. Since Flash is obsolete, do you mean something else?

Yes, I mean something else, namely all sneaky cookies not visible in settings>privacy security>delete all cookies when you close firefox browser. And I also mean all cookies hiding in stealth behind the scenes not visible in settings of firfeox>setting. And I mean any and all cookies that tracks me. I want zero cookies following me around.

I meant any cookie that tracks me around the internet not seen in settings but lurking stealthy, not visible in settings, perhaps even residing in a folder or directory.

Cookies are a specific technology. Local/offline storage is a specific technology. Both should be cleared by that setting. If there is some other technology that sites could use to detect a previous visit, let us know what it is.

If settings in firefox suffices then how come there are a ton of add-ons offering cookie removals? Which folder do the folder for all tracking cookies reside in on a linux? Is there a way to check if they are all gone? Is it worth getting an add on versus just sticking with setting delete all cookies?

If "Manage Data" is empty, does that mean there is no stored cookies in "cookies.sqlite"?

Are you familiar with linux?

Note that current releases can partition cookies, this means that cookies created by a third-party website can only be used in the website where they were created and can't be used to track you (each website will have its own cookie).

As far as I know, yes.

No, I'm definitely a Windows person.

If that's the case, is there any point in getting Ghostery add-on, and other similar add-ons?

You don't need an add-on to delete cookies. Each add-on does different things. For example, a main feature of Ghostery is to modify pages in real time.

Is viewing something in Storage Inspector's>Cookies the same thing as looking within Cookies.sqlite? I see only mozilla.org under Cookies using Storage Inspector. It's the only website I am viewing as of writing. Does Storage Inspector>cookies show me all the current cookies tracking me?

Helpful?

cookies.sqlite only stores persistent cookies and you may have to close Firefox to ensure that cookies are flushed. The Storage Inspector also shows session cookies and data stored in local storage (indexdDB).
