Just for the sake of jogging memory (as I just forgot about this and was trying to figure out what I did wrong):
SeaMonkey 2.53.7 en-US/zh-TW users need to manually upgrade to 184.108.40.206.
Or, for the sake of ‘fun’, just install 2.53.8 and have the system upgrade it to 220.127.116.11. Why would you do that? *shrug* For <something> and giggles.. Just so to prove it works.
