IMO we should remove the accepted answer, from How can I use Netflix on Ubuntu?. The 2nd most-voted answer is clearly more correct and supported by Google/Netflix.
Right now the only supported way to use Netflix is to use Google Chrome, as the second answer recommends. Firefox 49 (due next month) also allows for native Netflix. The accepted answer recommends a PPA and installing WINE, and the netflix-desktop package only even supports up to 15.04
