Multiple security issues were discovered in Firefox. If a user were
tricked into opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service, re-enable
camera devices without an additional permission prompt, spoof the browser
UI, or execute arbitrary code. (CVE-2021-29959, CVE-2021-29961,
CVE-2021-29966, CVE-2021-29967)
