    "Firefox now blocks third-party tracking cookies by default for all users."
    That's nice. However, I'd rather use third party products such as Privacy Possum. I do not trust FF to do things right. After all, FF uses Google's SafeBrowsing which allows Google to know which sites FF users go to.
