Mozilla, on the other hand, released Firefox 156 with fixes for 73 vulnerabilities, including 29 high-severity bugs. Many of these flaws are use-after-free and privilege escalation issues, alongside sandbox escapes and site isolation weaknesses.
Google has not yet disclosed the monetary rewards paid to external researchers who identified these vulnerabilities, with only two rewards totaling $2,500 being revealed. Mozilla’s update also includes fixes for Thunderbird 156 and 140.16, and Firefox ESR 153.3, 140.16, and 115.41.
