Earlier this week, Mozilla issued critical security patches to Firefox to fix critical vulnerabilities, CVE-2020-6819 and CVE-2020-6820, that can allow a hacker to take over a computer.
According to the Mozilla post on this topic, “Technical data includes information about your Firefox version and language, device operating system and hardware configuration, memory, basic information about crashes and errors, outcome of automated processes like updates, safebrowsing and activation to us. “ Which sounds okay if the data is anonymized but your IP address is reported as well.
