Firefox TV
You can download silk browser (FireTV stock browser) from xda and I find that it works really well
Puffin now requires a subscription apparently, so not that.
Is there any "usable" browser for Android tv at all?
I prefer Jio Page Web Browser as it supports downloading inside browser along with chrome bookmark synchronize and perfectly works with the android tv remote. You can check out here to install it on android tv https://bit.ly/3lYuemE
Oprah because it has full dark mode
Android System Webview 🤣
