Netflix blocks Fedora users from watching movies and TV shows using the Mozilla Firefox web browser, despite the fact that both Mozilla and Netflix claim that Firefox 52 at least should support Netflix’s updated HTML5 player on all Linux-based operating systems. Users reported that they are being redirected to the Silverlight player instead. Despite his efforts to contact the Netflix customer support and explain the issue, they appear to be clueless how to solve the problem. So after some more research, Jiri Eischmann discovered that Netflix doesn’t allow custom User-Agents on its video streaming plaform on Linux, which means that not only Fedora users are affected, but also those who use openSUSE, Debian, or even CentOS.
