Best secure and privacy web browsers:

A browser is software that is used to access
the Internet.
The best secure and privacy web browsers are as follows: 

1. Brave privacy browser 
The Brave browser was designed to make privacy simple. It is an open source browser built on top of Chromium , which means it's easy for Chrome users to make the switch.
However, the Brave browser say they does not collect any data about your online activities. Your data remains private and brave also makes trackers blocking easily. It automatically blocks all third-party and advertising cookies. Brave also features finger print protection in the browser. 

2. Tor browser 
Tor browser is the best option if privacy is your best concern. The Tor browser is based on Firefox, but it has been stripped down and specially calibrated to run on the Tor network.
When you use Tor, your traffic is encrypted three times and bounced between three Tor servers before it reaches your desired website. So no server has access to both your IP address and the website that you are also visiting. In every time you close your session, the browser deletes your cookies and browsing history. It also prevent the tracters who are tracking and block itself.

3. DuckDuckGo Browser 
DuckDuckGo browser, your Browsing history is not leaves your device. It deleting your entire browsing history is as easy as tapping a single button. It automatically blocks ads, stops third-party trackers, and ensures HTTPS Encryption on all sites where that's possible. This makes it easy for you to evaluate how much data is each website collects from you, with and without DuckDuckGo's protections, at a single glance. 

4. Epic privacy browser 
Epic Privacy Browser is also a privacy security browser. The app includes an ad blocker, HTTPS Everywhere, and every browsing sessions is in incognito mode. Additionally, it comes with an encrypted proxy via VPN with eight servers around the world. We also like the tracker counter. It reminds how much of trackers are blocked and howmany ads are showing , that is blocked. Now it is popular in play store.

Note: I am not promoting any browser. Its just a general Information.
