The tor browser is the most easy way to surf the internet anonymously . It is very very easy to install and it uses duck duck go as its search engine. The service is very good as you can mail its employs and get the easy answers of your questions.
It gives you three layers of ip which is really useful. But the thing which you need to note is that you should not maximize its window as if you do so you can be traced. It is also very easy to use and you can also surf the dark or deep web with this browser. but remember do it only in a legal way.
