Fact is, privacy on the Internet is an illusion.
Which is why I can never run for President.
privacy still exist at some point by the simple fact that company databases are independent
your browsing history doesn't transfer from one website to another magically ...
also some simple and not so simple actions can improve your privacy :
-nowadays paid VPN step by step solutions are common place (meaning there is several actors providing such services, enough for a potential client to have some choice in the matter), no one except the company behind it can relate what you're doing with who you are
some also advertise not keeping any history...
-plugins may improve your privacy : like, for example, noscript who prevent javascript from executing, and actually reinforce your privacy by preventing such scripts to communicate with their servers. the bad news though is that a lot of adds rely on javascript which means denying websites a source of revenue ...
this website for example uses crackerjackmack.com, googlesyndication.com, google.com & doubleclick.net
That said when you deny 99% if javascript from webpages you may actually notice that the web becomes a really fast place & your browser less crashable /CPU intensive & all that :roll:
-use IxQuick instead of google : no history kept of your searches ... HTTPS possibility ...
-many more that I'm either not aware of, or didn't remember at the time of this thread creation.
