I have been getting this failure trying to update firefox for a few days, 
is anyone else seeing this?

mozbuild.frontend.reader.BuildReaderError: ==============================
ERROR PROCESSING MOZBUILD FILE
==============================

The error occurred while processing the following file:

     /usr/ports/www/firefox/work/mozilla-release/config/external/moz.build

The underlying problem is we referenced a path that does not exist. That 
path is:

     /usr/ports/www/firefox/work/mozilla-release/media/libvorbis/moz.build

Either create the file if it needs to exist or do not reference it.

===>  Script "../configure" failed unexpectedly.
Please report the problem to gecko at FreeBSD.org [maintainer] and attach the
"/usr/ports/www/firefox/work/mozilla-release/obj-x86_64-unknown-freebsd11.0/config.log"
including the output of the failure of your make command. Also, it might 
be
a good idea to provide an overview of all packages installed on your 
system
(e.g. a /usr/local/sbin/pkg-static info -g -Ea).
