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 bypass same origin restrictions, obtain
sensitive information, spoof the addressbar, spoof the print dialog,
cause a denial of service via application crash or hang, or execute
arbitrary code. (CVE-2017-5398, CVE-2017-5399, CVE-2017-5400,
