I don't like using the "hacks" for running Netflix on Kodi, so I stick with the tried and true Netflix webpage via Google Chrome until the official Kodi addon gets released eventually. In this instance I am using Manjaro Cinnamon on a dedicated home theater computer in 720p resolution for better TV use (hence the larger interface in the screenshots). Now you can go the long way around and make your own custom launcher, which will launch Netflix in app mode (no borders) using the exec command:
However there is a much easier way and I didn't even know you could do this in Chrome on Linux until today. Here's what you do:
1- Install the official Netflix app for Chrome (which is basically just a link to the website) here: https://chrome.google.com/webstore/detail/netflix/deceagebecbceejblnlcjooeohmmeldh?utm_source=chrome-ntp-icon
2- In your Chrome apps menu right click the Netflix app icon and select "Open As Window". This will tell the launcher to open in "App Mode" and also in a dedicated window.
3- While still in the right click menu, choose "Create Shorcuts". Then choose your desired entries (desktop, or applications menu, or both). A super easy way to make Chrome app menu entries without busting out MenuLibre or a text editor - this is Manjaro not Arch after all, who has time to do things the manual way!
4- That's it, just click your new desktop or menu entry that will be located in "Chrome Apps" in your menu. The dedicated entry will open up in "App Mode" independent of any other Chrome activities you have going on. And obviously you can use this method for any Chrome App, not just Netflix. This is working for me on both Cinnamon and XFCE.
