A simple step you can take to protect your privacy is to use scrapers like the Scroogle, the Google Scraper. With this search tool, you are able to search the Google database without divulging your search patterns to them; protecting your privacy, so your personal information is not sold to Google’s customers.
By default Scroogle is not available in the list of search engines on Opera or most browsers for that matter; so you must take one simple step to add and enable it under your Opera preferences. After you’ve enabled Scroogle, if you’ve selected it as your default search, you can simply type the search term in the address box.
As you can see, I typed friendika into the address bar and Opera offers to search for Friendika via Scroogle. Of course, you can also type the term in the window on the right-hand side of the address bar.
This is just one simple thing you can do to significantly improve your privacy.
