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 cause a denial of service, spoof the browser
 UI, trick the user in to launching local executable binaries, obtain
 sensitive information, conduct cross-site scripting (XSS) attacks, or
 execute arbitrary code. (CVE-2019-11691, CVE-2019-11692, CVE-2019-11693,
 CVE-2019-11695, CVE-2019-11696, CVE-2019-11699, CVE-2019-11701,
 CVE-2019-7317, CVE-2019-9800, CVE-2019-9814, CVE-2019-9817, CVE-2019-9819,
 CVE-2019-9820, CVE-2019-9821)

 It was discovered that pressing certain key combinations could bypass
 addon installation prompt delays. If a user opened a specially crafted
 website, an attacker could potentially exploit this to trick them in to
 installing a malicious extension. (CVE-2019-11697)

 It was discovered that history data could be exposed via drag and drop
 of hyperlinks to and from bookmarks. If a user were tricked in to dragging
 a specially crafted hyperlink to the bookmark toolbar or sidebar, and
 subsequently back in to the web content area, an attacker could
 potentially exploit this to obtain sensitive information. (CVE-2019-11698)

 A type confusion bug was discovered with object groups and UnboxedObjects.
 If a user were tricked in to opening a specially crafted website after
 enabling the UnboxedObjects feature, an attacker could potentially
 exploit this to bypass security checks. (CVE-2019-9816)");
