Here, downstream? I don't think there's much to get started other than

  $ svn co https://trillian.chruetertee.ch/svn/freebsd-gecko/trunk gecko-overlay
  $ (cd gecko-overlay; for d in */*/files; do rm -rf /usr/ports/$d; done)
  $ rsync -aC gecko-overlay/ /usr/ports/
  $ cd /usr/ports/www/firefox-nightly
  $ make

or

  $ hg clone https://hg.mozilla.org/mozilla-central/
  $ cd mozilla-central
  $ ./mach bootstrap || (cd /usr/ports/www/firefox; make depends)
  $ ./mach build

If you can code (mostly C++ and make) there's an unordered list of ideas
in [1]. Some items may help chromium@ team as well such as OSS audio [2]
in WebRTC code.

No clue but I suspect other gecko@ members don't want to commit a port
that needs frequent updates. To make matter worse firefox-nightly often
depends on new version of NSPR/NSS or changes in bsd.gecko.mk.

Maybe Mozilla bug 419470 but for jemalloc3. I can't confirm because my
PGO build crashes due to libc++ vs. libstdc++ conflict.
