 We could think about backporting the sec-critical fix shipped in Firefox
 58.0.1:

 https://hg.mozilla.org/releases/mozilla-
 release/rev/c2db4a50dc5c93b44852d9a5201f7ec062ecc6cb

 ESR 52 got audited and this issue was not found there. We could use the
 backport as a defense-in-depth as it closes out a whole attack vector. The
 patch is largish, though.
