Vivaldi's Ruarí Ødegaard managed to create a handy script that would allow you to watch Netflix movies on Vivaldi, as well as any other Chromium-based web browser.
As you're probably aware of by now, Netflix only supports the Google Chrome and Opera web browsers when we talk about watching movies streamed via their online platform on Linux kernel-based operating systems. On Windows and Mac the there are more browsers supports, including Mozilla Firefox and Safari.
That is not the case for Linux users, whose open source and free personal computing platform is not even mentioned on the Netflix website. Therefore, if you're using a GNU/Linux distro and you want to watch Netflix movies, you are kind of forced to use the Google Chrome or Opera web browsers, though only the first is fully supported.
Here's how to watch Netflix movies on Vivaldi and Chromium-based browsers
If your web browser of choice is Vivaldi, which is based on the open-source Chromium project, or any other web browser based on Chromium, including Opera, you can use a simple script that you can run in a terminal window to fetch Google Chrome and extract the Widevine Media Optimizer plugin.
For those not in the known, Widevine is a browser plugin designed from the ground up to be used by various web browser for viewing of premium video content. It would appear that the script works well with any Ubuntu/Debian or Red Hat/Fedora-based operating system via DEB and RPM binary packages.
The script is availabe for free on GitHub.
If you want to use Netflix in @vivaldibrowser for Linux and don't want to Chrome installed, this should do the trick https://t.co/wBu4W3lCFI — Ruarí Ødegaard (@ruari) July 15, 2016
