I'm a Chrome user, a Google Search Labs user, but also a fan of https whenever/wherever possible to make sure what I'm doing is secure between my computer and the server responding.
I obviously have Google set as my default search engine, but wanted to have the https version as my default, with labs turned on.
As a side note, the reason I like Google Search Labs so much is because I can use keyboard shortcuts to open up results, shift-enter to open in a new tab, etc.
Anyway, it was pretty easy. I'm on a Mac, so I here are the steps to follow:
encrypted.google.comfor both the Name and Keyword inputs. Put in the url
https://encrypted.google.com/search?q=%sfor the URL input.
encrypted.google.comoption at the bottom of the list now. Scroll down to it, and set it as default
Boom! Now when you do searches through the address bar, rest assured it's been transmitted securely :)
