Videos do not play in Firefox

more options

No videos on any platform will play when I try to open them in Firefox. They are forever stuck on the thumbnail image of the video, and nothing happens when I hit play. I've had this happen a couple times and was able to resolve before by installing updates and uninstalling my Mozilla VPN, but this time nothing has worked. I've tried pretty much every solution I could find online:

  • Updating Firefox
  • Updating my computer
  • Running in Incognito
  • Running in troubleshooting mode
  • Allowing autoplay
  • Disabling hardware acceleration
  • Disabling addons
  • Clearing cache and data
  • Enabling/disabling DRM content
  • Installing Windows Media Pack

I'm running Windows 10, and videos seem to work fine in Edge, if that makes any difference.
