I download this from play store. I was free of cost I was bored from opera browser so I download this.it has Cloud Download which Supports downloading files in various formats And it make backup for them too. It is safe and secure browser then opera in my opinion. It also have ad-blocker which block all un wanted advertisements. Its very easy to install and use . It also have do not track option that can make our browsing much secure and safe from hackers .its better browser in my opinion. I recommended this to those who get bored from other browsers.
