 To fix CVE-2020-12388 and CVE-2020-12389, Mozilla set
 `security.sandbox.content.level` to `6`.
 The code to support that was backported to ESR: https://hg.mozilla.org
 /mozilla-
 unified/file/esr68/security/sandbox/win/src/sandboxbroker/sandboxBroker.cpp#l505
 Correctness and completeness of the backport should be audited.
