Log:
  www/firefox: temporarily disable OMTC to avoid crashes
  
  OMTC on X11 platforms uses BasicCompositor unless GL layers are
  also enabled. Change the default value of its pref in about:config.
  For now, bundled cairo is left as is pending more testing.
  
  No upstream bug as I cannot reproduce reliably to get the stacktrace(s)
  with a clean profile.
