See https://www.mozilla.org/en-US/firefox/49.0/releasenotes/ (.1 is for
a windows-only fix) - not that 'loop' (ex-firefox hello) was removed
from the browser.
- Fixes MFSA 2016-85
- Remove media/ffvpx/config.h patch, merged upstream/fixed differently in
bug #1239550
- Set media.autoplay.enabled to false by default, i'm usually wary of
changing upstream defaults, but this one is unfuriating with "the
modern web and all this funky video ads".. this one got support from
many.
- Add a blurb to README explaining how to enable/test e10s/multi-process
support.
