Comment (by jld):

 You might run into problems related to
 https://bugzilla.mozilla.org/show_bug.cgi?id=1386279 on Fedora, but the
 patch (https://hg.mozilla.org/mozilla-central/rev/c0838ed41842) is simple
 and should backport, although I haven't tried.

 Also, you may want to pick up https://hg.mozilla.org/mozilla-
 central/rev/c963d52551ab, which fixes CVE-2017-7794.
