[Mozilla Enterprise] GTK2 and Firefox 60esr

[Andrew C Aitchison]

Just a heads up for anyone running firefox on RHEL6
or clones (CentOS6, Scientific Linux 6 etc) or other
GTK2-based platforms.

Red Hat Enterprise Linux 6 uses gtk2 in firefox 52.8esr,
but I see from
   https://bugzilla.mozilla.org/show_bug.cgi?id=1278282
that Firefox 59 dropped the option to build with gtk2.

In https://access.redhat.com/announcements/3365141
Red Hat talk about plugins and addons with FF60 in RHEL6,
which suggests that they either aren't aware of the gtk2 issue
or have it under control (two very different possibilities).
