Off-topic: Encrypted Google search

Just use the newly rolled out "https://www.google.com" instead of regular "http://www.google.com".

But it looks like a very partial early roll-out:

1. "https://www.google.co.in/" simply goes to "http://www.google.co.in/". Seems to work only for ".com" domain.
2. I normally search from Firefox's search box with Google set as default; so I suppose I'll have to download a new option for this box? Not sure if one is available yet. Explicitly typing new URL, of course, works.
