Websites often store cookies and other data on your Mac. This data may include information that you have provided, such as your name, email address, and preferences. This data helps websites identify you when you return so the site can provide services for you and show information that might be of interest to you.

By default, Safari accepts cookies and website data only from websites you visit. This helps prevent certain advertisers from storing data on your Mac.

If you are using normal browsing window and browse , cookies will always be saved .

To clear cookies take cursor on top menu bar > click on safari > clear history

A window will appear , click on drop down arrows and choose as All history > click on clear history .

It doesn't seem to matter if I remove items from Favorites. Also I turned iCloud off figuring it might be a tethering issue. Below are the sites I'm unable to remove after following the recommendations here. Again, this has NEVER happened before in all my years as a Mac user...and is only an issue since the last update.

My system:

MacBook Pro (Mid-2012)

El Capitan 10.11.6

(...sorry, not to confuse the issue but I thought I was still using Yosemite, although I've since learned that Sierra users are having the same issue.)

Safari 10

Cookies and Caches help Safari run faster by storing relevant information locally.

But you can remove all those website data without any problem, it may even help.

Next time you visit the site, related cookies will be restored.

Websites one visits may have links embedded in to other web sites.

Those sites will store cookies in the cookies folder.

Cookies may not have the same name as the original website.

The homepage I have set, adds about 70 cookies.

A website may use service from other service providers.

When a user signs into ASC, a cookie from Badgeville will appear.

Cookies from websites added to AutoFill will appear automatically.

Websites that are related to widgets like Weather channel will reappear.

Cookies from built in search engines like Bing, Yahoo and other favorites like Facebook will reappear.

One of these may add additional cookies.

Cookies can be stored by Plug-ins and extensions installed on our Mac. There are Flash cookies.

Cookies from some of the bookmarked/favorites sites will reappear.

macOS stores cookies in different folders like Cookies folder, Databases folder, Local Storage folder, etc

It is not easy to track down these cookies.

There are”Evercookies” that are hard to delete.

This issue is not particular to Safari.

Compared to other browsers, Safari is more willing to show the presence of website data more willingly.

The “killer application” known as Internet/WWW presents it’s own peculiarities,

some of which we don’t like, but we cannot do much about it.

I wouldn’t worry much about this. Just empty caches from Develop menu and remove cookies and local storage

by opening Privacy pane of Safari Preferences, then clicking “Remove All” button.

I too have regularly deleted cookies and browsing history from every Mac I've owned back to 2005. This issue is new, with the Yosemite update. I have 4 Ever Cookies now. I will try the removal method you mention here, but surely there must be an easier way.

In a post I read earlier today, the below solved it for the OP.

Quit Safari.

In Finder go to Go menu and then Go to Folder

Copy and paste this ~/Library/Safari/Databases

Delete the contents of the folder

Launch Safari again and check if all is ok

I agree with Tradesmith45. The exact same thing is happening to me. First it was Labcorb, a site I do visit on occasion. I've been trying for over a week to delete that cooke. Today, another cookie (Citibank) which I never visited appears and will not delete. I've tried every suggestion in this thread (and more) and still they remain. I wonder whether this is the vanguard of the new policy signed by POTUS last week allowing Online companies to collect data on us? In other words, we may see more and more of this,
