You can download that webpage as a file and run that file on an offline computer with internet explorer.  You don't need to be connected to the web to use IE.


YES you could, download bitaddress.org, disconect your computer, create it and it's... offline until you reconnect your computer to the web..... It's only semi cold using this method.  As I said if your comp has malaware it's just going to record your keystrokes and forward it to the hacker when you reconnect.

HOWEVER this method will stop people that are connect to your comp watching it or just sending live key strokes. 

Semi cold is way better than hot.

Personally I would use Electrum. Been using it for almost a year now and so far I haven't encountered any bugs, not to mention it is very newbie-friendly (at least for me.)

Btw, what kind of "emergency" are we talking about here?

Then blockchain.info won't be much or any more secure than those options if you access it with your computer.

I think it mostly depends on the amount you intend to keep in a wallet. Web wallets should be considered 'hot', holding just enough for what you need to use daily (check out Coinbase). Mobile wallets are also considered hot (check out Bitcoin Wallet on Android, Breadwallet on iOS or Mycelium). Any considerable amount of coins should be stored in a 'cold' wallet - one without access to the internet (check out Paper Wallets, Hardware Wallets or specialized software like Armory).
