With little fanfare, Amazon launched its Silk web browser for Fire TV, allowing users with Fire TV, Fire TV Stick, and Fire TV Edition televisions to surf the web from their big screen. The app offers several standard web browser features, like the ability to search or enter URLs, access bookmarks, move forward or back, save passwords, and more. It also uses Bing.com as the default search engine, and supports searches via voice, thanks to its integrations with Fire TV’s voice remote.

Overall, however, the browser is a fairly bare bones app that doesn’t seem like it was carefully customized for use on a television’s screen. But then again, browsers aren’t really a great app for use on TVs in the first place.
