Scroogle instead of Google
Every time you use goolge they keep this information a long time. At the moment google is everywhere. It is not only a search engine with email accounts an you private page. Firefox use google to validate the page you want to visit. Of course this is a nice feature, but in my opinion this company gets too much information about you.
However I hope you don’t misunderstand me, because I think google is a great company, but you shouldn’t give them all infos they want. One point how you can use the quality of google but don’t give them too much information is to use
Scroogle as search engine. In the background they use google too, but without sending cookies and they save the history only 48h.
