Well, IE8, as well as some other browsers, makes it easier. If you want to browse and not have other people find out where you've been surfing, use In Private Browsing. You can start an InPrivate session either by; opening a new browser tab and clicking the Open An InPrivate Window link or by clicking the Safety Menu in the Command Bar and selecting InPrivatre Browsing. If you need their service USE IT. We want you be comfortable as you learn your new skills for having people respect you and treat you the way you should be treated.
Several other browsers strive to do the same--but the system is imperfect, so if physical safety is a problem, don't trust the system, according to a company that sells protection software.
InPrivate Browsing" in Internet Explorer, "Incognito mode" in Chrome, and "Private Browsing" in Firefox and Safari all strive to do the same two things: make it impossible for users of the same computer to figure out which sites the browser has been used to visit, and make it impossible for sites to know whether or not a particular user has previously visited them.
The researchers found that the browsers' protections were imperfect. Browsers did not properly isolate their private sessions from non-private ones, with the result that suitably crafted sites could trace visitors between private and non-private sessions. Sites could also leave persistent indications that they had been visited, allowing visits to be detected by local users.
In any case--although not perfect--if you pay attention you can serf safely.
