Roku TV does not have its own web browser. However, you can still surf the internet on your Roku by using the screen mirroring feature. To do this, you will need to download an internet app like Opera, Poprism, Web Browser X, or Chromecast from the Roku app store. Once you have downloaded the app, you can mirror your screen from a device that supports web browsing, such as a smartphone or tablet, to your Roku TV. This will allow you to browse the internet on your TV screen.
