It looks like users of the Greasemonkey extension got one more reason to jump for joy. Thanks to this handy script, you can eliminate the ability for folks to track your searching habits.
So to alleviate that at least a little bit, I have written a little Greasemonkey extension that routes the searches you would normally make on Google, Yahoo!, or MSN through a secure search proxy over at http://www.blackboxsearch.com.
Just install Greasemonkey, install the script from here (http://www.nemik.net/blackboxsearch.user.js) and visit your Google, personalized googe.com/ig, Yahoo, or MSN page as normally. But whenever you do a search it will go through the anonymous proxy so that Google and others cannot keep track of your searches.
