  • Various security fixes

  • Firefox crashes with 3rd party Chinese IME when using IME text


  • Due to an Apple touch bar bug, Firefox on recent MacBook Pro may crash when open for long periods or crash after resuming from sleep. Apple reports to have a fix for this in the currently unreleased OS X 10.12.3
