Netflix on default Chromium/Debian

[sp123]

Hi all!
I'm rusty on my linux and I'm trying to watch netflix on it for the first time. 
For some reason I thought that in the default distribution provided with PBP the Chromium browser already included support for Netflix. I can't watch it in Chromium nor Firefox. Is there additional setup necessary to get it going? I see that widevine is part of the updates that I run every once in a while so I'm even more confused by it not working.

If anyone could point me to how to get it running on the original distribution, would be appreciated.

Thanks!

There is script on the desktop you have to run to install wildvine.  I recommend you run the updater on the bottom of the screen then run the wildvine install script.

I am a novice. I assume I am supposed to give a command in the terminal to run this script.  Can you please let me know what exactly to type in terminal to install Widevine.
