I use firefox 83.0 on Ubuntu 20.04. Browser does not play videos on Twitter, Reddit or Netflix. Youtube plays some videos but some videos show error "your browser does not currently recognize any of the video formats available". I cannot find any viable solution. what should I do?

I installed chrome and it plays all the videos. So there must not be any problem in OS.

Firefox doesn't play videos compressed with patented video codecs like H.264 without an external assist. On Linux, I think Firefox looks for the FFmpeg package to be installed on the OS. Can you find that in your package manager?

Thank you for the solution. Package manager did not have ffmpeg and firefox started playing videos as soon as I installed it.
