Tor Browser is an internet browser based on firefox. It allows users to browse the internet anonymously. So, you can browse the blocked websites too. It hides your Ip address when you send or receive data from the internet. Your activity is encrypted so that you get privacy. Tor takes your internet requests and data through a huge network of hidden servers and the path is never the same
So by using Tor browser no website or organisation will be able to track your location or online activity.
