Firefox used to just play the videos within the browser but recently it stopped. It also stopped playing videos on streamable.com. I have media.wmf.enabled and media.play-stand-alone set to true.

Chosen solution

Try : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files and C:\Program Files(x86) Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

Reinstall with Current Release Firefox 57.0.2 with a Full Version Installer
