I do not understand.
Why does F-secure support say that F-secure Safe Search only work with Google as search engine?
If i have for example Bing as my search engine, i get the same information about the search result?
Safe Search is just a web page that uses Google as search engine and can be used by people that don't have F-Secure, or has F-Secure but not the Browsing Protection part. What you are referring to is an option in Internet Security(Online Safety - Browsing Protection)
