Original advisory details:

 Multiple security issues were discovered in Firefox. If a user were
 tricked in to opening a specially crafted website, an attacker could
 potentially exploit these to obtain sensitive information, bypass Content
 Security Policy (CSP) protections, bypass same-origin restrictions,
 conduct cross-site scripting (XSS) attacks, cause a denial of service, or
 execute arbitrary code. (CVE-2019-5849, CVE-2019-11734, CVE-2019-11735,
 CVE-2019-11737, CVE-2019-11738, CVE-2019-11740, CVE-2019-11742,
 CVE-2019-11743, CVE-2019-11744, CVE-2019-11746, CVE-2019-11748,
 CVE-2019-11749, CVE-2019-11750, CVE-2019-11752)

 It was discovered that a compromised content process could log in to a
 malicious Firefox Sync account. An attacker could potentially exploit
 this, in combination with another vulnerability, to disable the sandbox.
 (CVE-2019-9812)

 It was discovered that addons.mozilla.org and accounts.firefox.com could
 be loaded in to the same content process. An attacker could potentially
 exploit this, in combination with another vulnerability that allowed a
 cross-site scripting (XSS) attack, to modify browser settings.
 (CVE-2019-11741)

 It was discovered that the 'Forget about this site' feature in the history
 pane removes HTTP Strict Transport Security (HSTS) settings for sites on
 the pre-load list. An attacker could potentially exploit this to bypass
 the protections offered by HSTS. (CVE-2019-11747)");
