1. Unknown Cookies
When I tried a self-paced reading experiment, I found, by Google Chrome Developer Tool, cookies called
TEST, both of which were from
farm.pcibex.net. Moreover, by the cookie indicator on Google Chrome (an icon of eye on the right side of the search box),
I found that unknown six third party cookies were blocked when I turned on the blocking function.
