Tor Browser isolates each website you visit so third-party trackers and ads can't follow you. Any cookies automatically clear when you're done browsing. So will your browsing history.

Tor Browser User Agent
Tor Browser prevents someone watching your connection from knowing what websites you visit. All anyone monitoring your browsing habits can see is that you're using Tor.
Tor Browser aims to make all users look the same, making it difficult for you to be fingerprinted based on your browser and device information.
User agent is a HTTP request header string identifying browser, application, operating system which connects to the server. Not only browsers have user agent but also bots, search engines crawlers. Headers are easy to alter with cURL, and copying the User-Agent header of a legit browser could do the trick. In the real world, you'd need to set more than one header. But it is not difficult to artificially forge an HTTP request with cURL or any library to make the request look exactly like a request made with a browser.
Your traffic is relayed and encrypted three times as it passes over the Tor network. The network is comprised of thousands of volunteer-run servers known as Tor relays.
