While the existing code functions correctly with or without electrolysis enabled, we improved it (see the check in comment for details). The fixup patch is here: https://gitweb.torproject.org/user/brade/tor-browser.git/commit/?h=bug21850-01&id=3d3272e7b56ed23c18f3ba1f3fbb1821118e164c

We forgot about comment:9. Here is an additional fixup patch that forces about:tbupdate to always be loaded in a content process: https://gitweb.torproject.org/user/brade/tor-browser.git/commit/?h=bug21850-01&id=7a7c6b380c95a00f3091aa8f79c24bd76a0a2cbc

It seems safer to do this and should not cause any harm (we already force the same behavior for about:tor).

Moving reviews to February.
