I sideloaded Chrome and Firefox a few months ago using the sideload launcher app (https://play.google.com/store/apps/details?id=eu.chainfire.tv.sideloadlauncher&hl=en https://play.google.com/store/apps/details?id=eu.chainfire.t...), but the browsers have issues, mostly UI / UX tweaks to make them usable with the onscreen keyboard, Android TV remote etc. without buying a bunch of extra hardware. The easier work around at the moment is to cast from a laptop.
