I was just testing the different browsers to basically play youtube videos on tv. I just notice that only chrome has that option. Microsoft has an option to cast but the tv didn't get detected. Firefox, I can't seem to find any option. At least not yet. I thought this was interesting since I wanted to start using a different browser to test. As you can see the option in chrome, it's on the bottom right, next to the other options. The others may have something but more hidden. I don't know.
Chrome
Firefox
Edge
