As with the instawallet style URLs, users should not be recommended to use this kind of instant access in browsers.
eg.
Google Chrome records and sends to their servers what the user types in the omnibox to "bettter serve" the results. So user's seed will be leaked to Google's servers and added to Google search results as already happened with instawallet wallet private URLs that holds the private keys.
Your wallet doesn't have a password to access coins, so you'll end up making the same mistake.
