Comment:

 We backported the three patches. They are all on the bug12523-01 branch
 within brade's tor-browser repo.:
 https://gitweb.torproject.org/user/brade/tor-
 browser.git/commit/?h=bug12523-01&id=da628e779cfcbc70e6dde45b09bdc2495d10570a
 https://gitweb.torproject.org/user/brade/tor-
 browser.git/commit/?h=bug12523-01&id=d733d46f5c5f9f1a73a9f4904d542a44bc984a0d

 browser.git/commit/?h=bug12523-01&id=70bfa694be143dc5665379e3634d9a41f3d5d754

 The first two applied cleanly but we had to do some manual work for the
 third one (Mozilla refactored some code under js/src/asmjs).
