And there are a few ones so I'm guessing yours does not have such. Even if it did, these Smart TV browsers are not giving us a PC like browser and folk are sometimes wanting that. So there's a few ways to add it later.
The cheap way is one of those Android HDMI sticks and a smart(er) BluRay player. Keep in mind these are not like a PC's browser.
