Some websites that have a lot of visitors are running programs (scripts) called "Session Replay Scripts" .
These scripts can record your every keystroke that you print, even if you paste any text.
Websites claim that they use these scripts to test how their visitors react with the website but they record every session of surfing by every user.
Bonobos, Walgreens, Fidelity are using these scripts and after this study some of them stopped using it.
To protect your self you have to be sure that all websites using HTTPS, and download an extension called AdBlock Plus.
