I installed Ubuntu 18.04 64-bit and enabled DRM in Firefox. When trying to watch Netflix, I get the following errors:

Oops, something went wrong...

Netflix video player unavailable

We're having trouble playing Netflix in your browser. Please make sure you're on an official version of Firefox.

Error Code: F7355-1204

I'm using the version of Firefox that came installed with Ubuntu. How do I play Netflix videos on 18.04?

In order to watch netflix with firefox under Ubuntu 18.04, you need to make sure that you have DRM enabled in your firefox settings (Go to settings, scroll down, check play drm-controlled content). Also make sure you have the libavcodec-extra package (from the universe repository) installed. In order to install libavcodec-extra you should have the universe repository enabled:

sudo add-apt-repository universe

Then install the libavcodec-extra package:

sudo apt install libavcodec-extra

I found this fix at Netflix support site. I have the HTML 5 theme enabled and Silverlight theme was also added but not enabled.

I also have the following plugins enabled, OpenH264 Video Codec, shockwave flash, and Widevine Content Decryption Module.

Netflix is now working perfectly from Firefox browser in Ubuntu 18.04.
