In respect of privacy on internet there are a lot of tools and techniques available to minimize your traces. Tor Browser is one such “tool” if you like to appear anonymous while browsing the web.
Privacy tools.ic has made a rather nice list of VPN providers, browsers, configurations, ad-ons, even OS do’s and don’ts. Check it out here.
By the way, if you don’t use it yet, test Firefox with Web Developer ad-on, or all extensions for Chrome that can be used to show what sites you visit can see and not.
