Video-on-demand has become popular thanks to services like Netflix. You already know what it's all about: by paying a monthly subscription you'll have access to a complete catalog of series, movies and documentaries that you can play on your computer through your browser or official applications for PC, Android smartphones or tablets, iPhones and SmartTV.
Netflix's extension for Google's browser
The extension Netflix for Chrome allows you to integrate into Google's browser your user account for free. Therefore, it allows you to access all the contents straight from Windows or Mac, although you'll obviously need a subscription to the service.
You can watch Narcos, House of Cards, or any other series, straight from your browser.
Furthermore, you should know that rather being some kind of standalone application or development it's more like a shortcut to the web. However, you can control it just like any other application you usually use on this browser.
Therefore, forget about watching Netflix offline or getting out of paying for the service.
