Since last week, Firefox Nightly has process separation enabled by default: https://groups.google.com/forum/#!topic/mozilla.dev.platform/OQCFwGn5sXg https://groups.google.com/forum/#!topic/mozilla.dev.platform... A patch to enable the content process sandbox by default was posted for review a few days ago: http://bugzil.la/928044 http://bugzil.la/928044 The sandboxing implementation isn't complete yet (it requires separate work for each OS that Firefox supports) and there's a significant list of known issues before this can be turned on in release builds, but there is now a team working full-time on this project, so it should improve quickly.
