Netflix on Linux without Silverlight
Netflix HTML5 Player
Netflix is currently the only VoD provider to offer an HTML5 player as well. It works thanks to the full implementation of Encrypted Media Extensions (EME) [10] – but only with Chrome, Internet Explorer, and Safari; that is, on Linux, you must use Google Chrome. Open source browsers Chromium, Firefox, and Opera all lack the EME extension.
Having Chrome as your browser is not enough, however. If Netflix detects (via a message sent by the browser user agent) that you are using Linux, you again end up on the website with the system requirements. Only after tweaking the browser identification using the User Agent Switcher extension [11] for Chrome (Figure 3) does Netflix finally deliver HTML5 video. To accomplish this, install the extension and then set up a matching user agent in the add-on options as per the information in Table 1.

On rolling release distributions (e.g., Arch Linux), Netflix then loads the Linux-friendly HTML5 stream (Figure 4). However, on older or even slightly dated distributions, such as Ubuntu 14.04, you need to install an update for the NSS library published on September 22 to help the browser handle the encryption technology used by Netflix (see the box "Netflix on Ubuntu 14.04").
Netflix on Ubuntu 14.04
Beyond Chrome and the right User-Agent string, Netflix on a Linux system also needs the Network Security Services libraries [12] by Mozilla, version 3.16.2 or later. However, the current Ubuntu 14.04 LTS only came with version 3.15.4. Therefore, despite Chrome and a matching user agent, the screen remains blank on Ubuntu – unless you have smuggled the version of the library used in Ubuntu 14.10 into 14.04.
After a discussion on the ubuntu-devel mailing list [13], Canonical quickly resolved this issue. The library update necessary for Netflix is now in the Security repositories of Ubuntu 12.04 and 14.04, and can be imported as normal security update. In case of difficulties with Netflix, you should thus check first to see whether your Ubuntu has appropriate libnss3
version 3.17-0 or later:
$ dpkg -l libnss3* | grep ii
If you already followed a popular posting on the web and manually updated libnss3 in Ubuntu 14.04, then you can use the commands in Listing 1 to install the original packages. If the download via wget
fails, then Canonical has probably revised the packages in the meantime and changed the version number. In this case, manually download the DEB packages for libnss3 [14], Libnss3-1d [15], and libnss3-nssdb [16] off the web.

(Make Your Own) Conclusions
Whether the movie and serial offerings from Netflix are superior to those of other VoD providers is something you can only decide for yourself – all of these services offer a free trial period in which to make your own conclusions. That said, the Netflix HTML5 player is a unique selling point for Linux users. Now that Ubuntu 12.04 and 14.04 can officially be updated to meet the system requirements for Netflix, the company has promised to make the user agent query more Linux friendly in the near future [17].
Now Netflix only needs to free itself from the grasp of Chrome for users to access the service directly in Kodi (formerly: XBMC), which would open up a whole new world to the Raspberry Pi. Mozilla would also have to complete its own implementation of EME, which was announced in May 2014 [18], making it the first open source solution for DRM in HTML5 video elements that would run on the Raspberry Pi.
