The latest Firefox update appears to break video playback on Linux. I am having issues playing video on Twitter, Facebook, and Locals. YouTube video still plays. I have not enabled any new ad blocking and have also not changed any settings. Looking at the Troubleshooting Information in Firefox reveals nothing that is suspect.

Let me boot to openSUSE. I don't do Facebook, but can you provide links to other videos not playing for you? What OS? What Desktop? X11 or Wayland?

Make sure you have the latest FFmpeg and libavcodec packages installed.

YouTube has a lot of formats available and Firefox can fallback to a codec your OS supports, but other websites may only offer a limited set of formats and can fail.
