Browser availabilty via an app on Roku
Roku needs a browser to access internet options. Firestick has apps. Please make a browser app available on Roku.
I often see this request for a browser for the Roku and am in disagreement with those requests.
First, eats up memory resources. A laptop/computer/mobile device better suited for browsing. Connect these directly to your TV via HDMI adapters/cables/wifi and you have a faster internet TV.
Second, there are TV's with built-in browsers if such is needed at integrated TV level.
Third, opening up the platform to browser function only introduces security concerns.
Fourth, as you mentioned, other devices already have this feature. Since these various streaming devices are relatively inexpensive, can simply add these additional devices to the TV and use the features of each one when needed.
Fifth, there are apps available in the Play/Apple Stores that will allow you to cast web video content to the Roku devices using a mobile device.

In any instance that I have come across, I have found connecting my laptop directly to the TV via HDMI cable is the easiest way to have "internet browsing on my TV". I do not see any instance where having a browser available to the Roku device would be a better solution.
I sure am open to hearing the opposing opinion though.
