[mzup]

seriously, is there ANY reason for this add-on any more?

 I don't understand what you mean? Is netflix access built into Kodi 18? I am on 17.6 so this is why I don't follow. 

@mzup; i'm not sure if it is built-in or not, but i know that the following plugin works natively with kodi 18 (no screwery with browser, window manager, etc- just have to get widevine lib):
https://github.com/asciidisco/plugin.video.netflix

I think i read somewhere this plugin was going to make it to the official reps, but i could be making that up in my mind.
Maybe someone with more knowledge can speak up.. 

That looks like it is for non windows systems. I am on windows so that doesn't work for me.  thanks though. Will wait to see about Kodi 18.
