Whenever I try and play videos on Facebook, my university website or any other website I could think of the video will not play. Sometimes there is a "no video with supported format and mime type found" error. I have reinstalled, started in safe mode, deleted all cache and cookies and nothing has worked. I am running Ubuntu 18.04.1 and Firefox 61.0.1

If you check YouTube's format support page, is support for H.264/MP4 found or missing?

Note: Firefox doesn't include MPEG decoding (it's patented), so if that isn't already in your distribution, you might need to install additional software. Not sure if there are useful links here or whether a Linux user will need to jump in: Fix common audio and video issues.

It likely installed the needed FFmpeg package that HTML5 players use as Gstreamer has not been used for quite a while now. FFmpeg packages may not be installed during a Linux distro install.
