How to play Geforce Now using the web browser.
On August 2020 Nvidia added GeForce NOW support to Chromebooks, which means that you can play Geforce NOW using the Chrome browser on Chromebook laptops.
This means that if you manage to spoof the user agent of your browser you can play GeForce NOW on Linux, Windows or Mac OS X just using your Chrome or Firefox browser.
If you use Chrome or Edge all you just need to
install this extension and if you use Firefox
install this extension. Then just go to
play.geforcenow.com, login into your GFN account and start playing!
The extension only changes the browser user-agent when you visit play.geforcenow.com with the purpose of making Nvidia believe that you are running a Chromebook laptop. Thanks a lot to
