: Most widespread cookies What are the most widespread cookies among population? One example could be _ga cookie, but are there any others public cookies that almost everyone has in his/her browser?

It does not really matter what the most widespread cookie is as you can only access cookies set by your site for your site. Trying to access other cookies is classified a security issue and so browsers won't allow you to access cookies that have not been set under your domain name.

In other words if your domain is example.com and you set your cookies at that level then you can access the cookies from


example.com example.com blog.example.com
etc


But you can't access any cookies from other domains such as example2.com, notmydomain.com, etc.
