What's in the latest Firefox update? Firefox 71 plays picture-in-picture catch-up
Mozilla this week released Firefox 71, touting a picture-in-picture video mode and new ways to preview a VPN (virtual private networking) service that will be offered to customers next year.
Security engineers included patches for 11 vulnerabilities, six marked "High," the second-most-serious threat rating. None were tagged "Critical." Some of these flaws might be exploitable by cyber criminals, Mozilla said. "This could have caused heap corruption and a potentially exploitable crash," the firm noted of one vulnerability, labeled CVE-2019-11745.
