Firefox without dbus

[Kazuo Kuroi]

Hi,

As a former Palemoon user on FreeBSD I am contacting you regarding if it's possible to fix the Firefox build to not pull dbus in as a dependency.

Another OS, kisslinux, does not require dbus to be installed. I am aware that GTK3 pulls this in as well and have contacted gnome@ as well. 

The details kisslinux uses are in this repo: https://github.com/kisslinux/repo/tree/master/extra/

Best regards.
