Brian,

I have done some of the same. I sent some of these patches to mozilla
maintainer. I also started making a mozilla-gtk2 package. I was doing this
so I could build Epiphany (which has been unsuccessful). I've been told
that fixes may be found in FreeBSD ports, but I haven't looked yet.

My patches for mozilla below. My mozilla-gtk2 pkgsrc (mostly based by
copying mozilla, like patches) is at
